Car brand spark plugs. Brisk spark plugs

A modern internal combustion engine is equipped with an electronic control system with many sensors. With their help, control over the processes of combustion of fuel in the cylinder is carried out.

The operation of the engine largely depends on the correct selection of spark plugs, including the make of the car. Errors in this matter can lead to and reduce the dynamics of the vehicle.

Spark plugs are designed to ignite the air-fuel mixture in the engine cylinder. Arson is carried out due to the formation of a spark between the electrodes of this device when a high voltage electric current is passed through it.

The stability of this device depends on several factors:

• design features;
• materials used in the manufacturing process;
• compliance of the parameters of this device with the characteristics of the engine.

Automakers recommend certain types of spark plugs for specific car brands. The main characteristic of this device is the glow number, which depends on the heat transfer efficiency of the structure and the so-called thermal cone. This parameter is determined in a special laboratory for each type of product.

The heat number of a spark plug is, in fact, an integrated indicator of time. After a certain period, the parts placed in certain conditions of the device are heated to a temperature at which the mixture spontaneously ignites. This phenomenon is called glow ignition, this process proceeds uncontrollably, in some cases even engine operation is noted after it is turned off.

Video - manufacturing process:

The optimum temperature for stable operation of the plug is in the range of 500 ⁰C to 600 ⁰C, when carbon deposits do not form on it. There is a certain amount of oil in the engine cylinder, which inevitably gets on the electrodes and insulator. At the above temperatures, it burns completely and without residue. Thus, the candle is self-cleaning and its stable operation is ensured.

The method of selecting spark plugs by car brand

On components of domestic production in the marking there is an indication of the size of the thermal cone of the product. However, practice shows that this parameter alone is not enough for the correct selection of spark plugs by car brand and engine model.

To solve this problem, machine manufacturers and component manufacturers offer possible replacement options.

The technical documentation for the car indicates the recommended brand of spark plugs. In turn, the product packaging indicates a list of machine models on which it can be used.

This approach is only good if there is a manual for the car, and auto parts store employees know the assortment well. Unfortunately, often a motorist has to rely solely on his own strength.

When selecting candles according to the model installed on this brand of car, the owner’s actions are simple:

1. the product is unscrewed from the engine in compliance with safety measures;
2. the marking is read from the candle body;
3. according to the index in the store, the necessary product is selected.

This technique can only be used if the car owner is sure that the correct spark plugs are installed on the car.

The technical documentation of the car indicates a list of recommended spark plugs at the time of its production. During operation, component manufacturers can offer other options that are suitable in terms of parameters.

For domestically produced cars, at one time special tables of interchangeability of spark plugs were compiled, which included the products of foreign companies.

At the present stage, the process of selecting components for a car is significantly influenced by information technology. There are special services on the Internet that allow you to choose the right product from an extensive range of products. In this case, the selection of spark plugs for a car should not be limited only to the formal conformity of the marking recommended by the manufacturer.

Selection specifics

There is a significant number of counterfeit products on the spare parts market, outright fakes of well-known brands. A completely logical question arises, how to choose spark plugs by car brand and not purchase a substandard device. Defective parts and fakes are found in the markets and in small stores much more often than in large specialized car dealerships.

It is impossible to give a full guarantee against the acquisition of a fake, but if the recommendations below are followed, the likelihood of such an event will be much lower:

• When buying a set of spark plugs, you should carefully examine not only the product itself, but also the packaging. The device must not have chips in the insulator and damage to the electrodes and other parts.
• In serious outlets there are devices for checking spark plugs. Of course, they cannot fully simulate the processes occurring in the cylinder, but such a test will not be superfluous.
• The presence of a product certification mark in an accredited laboratory is a certain guarantee of the product's compliance with the Russian standard.

If the selection of candles by car brand is carried out in online stores, then you should not hesitate to check the completeness and their compliance with the samples on the site upon receipt of the order. Inspection of each product from the set is mandatory, if necessary, the packaging is opened. Installing candles on the engine that are not suitable in terms of parameters is fraught not only with an increase in fuel consumption, but also with serious breakdowns.

Overview of online services for the selection of spark plugs

Online stores offer a large selection of spare parts and accessories for cars. How to choose spark plugs for cars online and avoid mistakes?

The order of operation of online stores with minor variations is as follows:

• the car owner makes an order by phone or directly on the site;
• the application is processed and transferred for execution to the delivery service;
• upon receipt of the goods, the buyer checks the completeness and pays off.

If necessary, store employees can provide assistance and select a candle for the car. To do this, the specialist must provide the following data: machine model, engine size and. Based on this data, the sales assistant can offer several options for products from popular manufacturers such as DENSO suitable for use on this model of machine.

In the Russian Federation, the most popular services where spark plugs are selected by car brand are the following sites:

• Electronic spare parts catalog from the Denso brand (LINK).

• Bosch spare parts catalog (bishka.ru/catalogue/svechizazhiganija).

• Selection of NGK products by car brand (LINK).

The purchase of a new set of spark plugs to replace worn ones will restore engine parameters and reduce fuel consumption. Timely and regular maintenance and repair of the car is a guarantee of extending its service life and trouble-free operation for a long time.

Recommended before a long trip

The stable operation of the engines of modern vehicles to a large extent depends on spark plugs. With their proper selection, the fuel in the car engine burns out as efficiently and efficiently as possible, which makes it possible to reduce fuel costs.

4 Selection of components for obtaining a spark - standard methods

On candles from Russian manufacturers, the value of their thermal cone is always indicated. In theory, we need to purchase a device with the same marking and install it on the machine. Unfortunately, this technique does not work. Knowing the size of the cone does not allow for a truly high-quality selection of products for a specific engine model and vehicle brand. The problem can be solved if we are talking about cars of the last 10–15 years of production (both imported and domestic). Manufacturers in the manual for their iron horses clearly indicate which candles can be replaced with factory components in case they fail.

And what about the owners of old vehicles and machines that do not have operating instructions? It is difficult to purchase the necessary spark plugs in this case, but it is possible, we select products for the car as follows:

1. We unscrew the old product from the motor.
2. We find the marking on the body of the part.
3. We go to the auto shop and select the appropriate item by index.

If the required model of the component is not available, we ask for advice from sales consultants. Perhaps they will be able to suggest how to replace the device of the type we need. Here we have to rely on their professionalism and good knowledge of the range of automotive products.

Note! The described method of selecting ignition devices is only suitable for cases where you are sure that the correct spark plugs are on the machine.

5 Choose and buy spark plugs in a new way!

Modern technology has made the life of motorists much easier. With the help of online services, they can pick up and order spark plugs without leaving their cozy home. There are many special sites on the network that sell a variety of devices for getting a spark. There are unique services among them, where the consumer can independently choose components, knowing the VIN code and engine size, as well as the brand of his car.

Many drivers select and purchase ignition devices on the NGK Internet site (https://www.ngk.de/nc/ru/podbor-produkcii/). A clear interface and a huge database of the site allows any vehicle owner to choose the part he needs by car brand. There is no easier way to find the desired element!

NGK is a very convenient, but not the only online service available to Russian motorists. We can also use BOSCH (http://bishka.ru/catalogue/svechizazhiganija/) and DENSO (http://www.denso-am.ru/elektronnyi-katalog/) electronic catalogs. They make it possible to select candles by car brand, company that produces spare parts, type and model of components. The child will be fine too!

Regular replacement of ignition devices is the key to long-term operation of the car. Feel free to follow this procedure. And then the motor of the car will delight you with its stable operation at maximum power. And you will forget forever!

A spark plug is a device that ignites the air-fuel mixture in an engine. Its incorrect functioning leads to three main problems: unstable operation of the engine, its complete stop, and excessive fuel consumption.

Main characteristics:

• Heat number.
• The degree of self-cleaning.
• Spark gap indicator.
• Number of electrodes.
• Thermal characteristics.
• Operating temperature range.

Each motor requires its own candles, their incorrect selection will lead not only to a deterioration in the operation of the motor, but also to other serious problems.

Main characteristics of spark plugs

In addition to general characteristics, such as service life (measured in kilometers) or price / quality ratio, candles have precise ones.

heat number

The main indicator that you should pay attention to. It shows at what level of pressure in the cylinder ignition is possible - the ignition of the mixture is not from the spark itself, but from contact with candles.

IMPORTANT! The heat number must necessarily match the number for a particular engine. Experts allow short-term use of candles with a higher CN than indicated in the specification for the motor, but categorically do not recommend candles with a lower number. Otherwise, the engine will be seriously damaged.

Degree of self-cleaning

Spark gap

This is the name of the gap between the central and side electrodes. Each type of candle has its own, it is not worth adjusting it. If it was changed as a result of damage or a manufacturing defect, it is more profitable to refuse such a candle than to try to fix it.

Number of side electrodes

The standard design assumes the presence of two electrodes: central and side. Now on the market there are 3- and 4-electrode. Their number increases the stability of the spark formation process, makes the engine work more stable. In addition, the more electrodes, the longer the candle lasts. The widespread belief that the more electrodes, the more sparks occur is erroneous. A few sparks occur in candles without side electrodes, but this type is not very widespread due to the high cost.

Working temperature

The norm for this indicator is from 500 to 900 degrees. A decrease will cause carbon deposits on the insulator, which will cause instability in sparking. Too high a temperature leads to uncontrollable glow ignition, which reduces engine power and shortens the life of the plug.

Thermal characteristic of a candle

The indicator divides candles into two types: “cold” and “hot”. "Hot" are intended for engines where a self-cleaning temperature is needed at low temperatures. Spark plugs with higher thermal ratings than those recommended by the manufacturer will cause uncontrolled glow ignition. "Cold" ones are used there, heating is needed below the glow ignition temperature at maximum engine power. Spark plugs that are too “cold” for this engine will not heat up to the required self-cleaning temperature, which leads to rapid wear.

Top 10 Best Spark Plugs

As in any other rankings, the distribution of positions in the TOP-10 depends on who made it. It is more effective to make your own rating based on the use of products of certain brands. In addition, the manufacturer usually indicates which car manufacturers he cooperates with.

So, Bosch candles are in all Toyota cars and a number of other giants of the global automotive industry. NGK works with Volvo and BMW. Champion supplies products for Suzuki and Volvo. Brisk - for Audi, Opel, etc.

In addition, different brands produce different types of candles. Therefore, in the case of 4-electrode candles, the manufacturer may be in first place, and in the ranking of 2-electrode candles, in fifth.

1. NGK B9Eg-3530. Leadership primarily because it is installed on most cars assembled in Russia. Accordingly, such candles are widely represented in retail. Cons - a large number of fakes of NLC.
2. NGK BKR6EIX (6418). Despite the high cost, it is popular in Russia. Recommended for new engines and quality gasoline.
3. Beru Ultra-X 79. The main advantage is the price / quality ratio. Lots of counterfeits.
4. Denso PK20PR-P8. Consistently high manufacturing quality, one of the best wear and spark erosion resistance on the market.
5. Brisk Extra Dr15Tc-1. High performance. Thanks to the original design of Brisk spark plugs, they significantly increase fuel economy and minimize the number of fakes. Minus - high price.
6. Bosch Platinum WR7DP. The position of the German manufacturer could be higher, but its products are designed for the German quality of fuel and roads. In Russia, you can't count on it. Nevertheless, they are durable - 55-60 thousand kilometers. Minus - a large number of fakes.
7. NGK BKR6EK (2288). Widespread, durable and economical. Competitive price. But there are too many counterfeit products on the market that are difficult to distinguish from the original.
8. Denso K20TXR. Due to the nickel coating, they are durable and resistant to erosion. Economical fuel consumption, reasonable cost. It does not work well if the engine is gas (HBO).
9. Beru Z193. Popular largely due to affordability. Focused on the average driver who does not like to drive at high speeds often. Not too durable compared to analogues. Due to the low price, they are practically not faked.
10. Bosch FR7DCX. Domestic products, developed by German engineers. Sufficiently high build quality, suitable for many Russian brands. Not very suitable for automatic transmission.

Marking

The marking contains data on the manufacturer, material, glow number, gap size and design features of a particular section. Difficulties with labeling are related to the fact that if in Russia it is one for everyone, then global manufacturers have their own. Compatibility tables of all or the most popular manufacturers in 99% of cases are available from sellers. Or you can find them online.

Replacement frequency

The standard service life of conventional candles is about 30 thousand kilometers. For those made using precious metals, it can reach 100 thousand. This is influenced by many factors, primarily the quality of fuel. Also among the negative factors are the temperature difference (compression / expansion of the case) and the humidity of the environment.

IMPORTANT! Signs of problems: the car twitches, the engine does not start immediately or stalls, fuel consumption has increased. Worth a look at the candles. It must be changed if: there is oil, soot on the electrodes, the insulator has changed color and become cloudy, or there is damage on it.

If you regularly diagnose the machine at a service station where there is appropriate equipment, it is easier to avoid problems.

Features when choosing spark plugs

The most important rule is to select candles based on your own experience. If it is small, there are a few simple rules to make the right choice:

• By size, the candle must be chosen exactly the same as that which stood earlier.
• The heat number is exactly the same as the old one.
• Multi-electrode candles are more durable.
• More expensive candles made using precious metals reduce gas mileage by 7%.
• The size of the gap between the electrodes. Experts recommend that it be within 1 - 1.3 mm.

How to determine the type of candle by car brand

First of all: in order to select spark plugs for a car brand, you need to read the technical manual. It also has replacement options. If the car was bought "from hand", you should carefully study the marking and search the Internet for information on how this candle fits the engine, which one can replace it with. For example, it is believed that Rekord candles are well suited for Opel.

You can seek advice from a car dealer or search for relevant information on the Internet. For example, “select Denso spark plugs by car brand” or “which SZ to put on Lifan 1.8”.

Selection of candles by wine code

Vin-code - identification number of the car from 17 digits. It contains information about the manufacturer, characteristics and year of manufacture of the machine. It is in the data sheet and applied by the manufacturer to the parts of the body that are least susceptible to deformation during an accident.

There can be several such places: the front left pillar of the body, the left upper part of the dashboard, under the floor covering under the driver's seat, under the hood, etc.

The easiest way to select spark plugs by VIN code is to use online services. For example, the easiest way to find denso spark plugs for a car brand is on the company's website.

Online services for the selection of SZ

To minimize the risks when buying candles through online services, you should first study user reviews about them. For this, large forums of motorists are suitable. There you can also ask questions and ask for recommendations. For example, “if there is a difference between candles for Mazda 6 2.0 and 2.3” or “denso power reviews”

IMPORTANT! Many such sites offer the help of a consultant. To do this, name the VIN-code and leave your contact details. After that, the seller contacts the client himself and helps to choose the goods for free.

For additional guarantees, you can try to find a service whose office is located nearby. This will make it easier to file claims in case of a conflict with the seller.

Immediately after the purchase is delivered, it must be opened (unless otherwise specified) and checked for originality and performance.

As in the case of other goods, one must understand: the more expensive it is, the better. However, in the case of candles, there are nuances. For example, putting the most expensive candles on an old GAZ or even relatively new VAZ models is not worth it.

When replacing an old candle with a new one, the latter must exactly match the size of the old one. The same applies to the heat number.

Multi-electrode SZ is more expensive, but more profitable. First, they give a better spark to the fuel. Secondly, if one electrode fails, it will be replaced by another. Thus, the candle will last longer.

The most expensive electrode is iridium, such candles last the longest.

Heat number of spark plugs

This is a characteristic of automotive ignition, showing at what pressure glow ignition begins to appear - ignition of the mixture from the candle body.

In Russia, there is a single CN scale - from 8 to 26. "Hot" candles - from 11 to 14, "cold" - from 20 and above. Foreign producers prefer their schools. To determine the interchangeability of candles, you need to find the appropriate tables on the Internet.

Not really

Reliable operation of the motor depends on many factors, including spark plugs. An incorrectly selected spare part can cause increased fuel consumption and a decrease in engine power. How to select spark plugs by car brand, and what to look for when choosing, read our article.

Characteristics of candles

The modern market offers a huge number of candles for sale, differing in configuration, material of execution and technical data. For each type of motor and car model, its own spare part is selected, in accordance with its characteristics.

Candles are characterized by a set the following options:

• Number of electrodes- their number in a candle (the most common parts with two elements).
• heat number - parameter that determines the thermal properties of the part. The higher this number, the better it works at critically high temperatures. In accordance with this parameter, candles are:

1. hot- glow number from 11 to 14 (for lightly loaded engines and measured driving);
2. medium- value from 17 to 19 (used in most vehicles with power from 100 hp);
3. cold- over 20 (for powerful turbocharged engines).

• spark gap- the distance from the central to the side electrode (the larger it is, the better the fuel ignites).
• Performance material- in most cases, candles are made of alloy steel with an additive in the form of nickel and manganese. Significantly increases the service life of the part, and at the same time its cost, the platinum coating of the electrodes.
• G dimensions - such as:

1. thread length- there are short -12 mm, medium - 20 mm and long - 25 mm models;
2. thread type- most often found on cars type M14 × 1.25 (where 14 is the thread diameter, and 1.25 is the thread pitch);
3. hex head size- modern values ​​\u200b\u200bare most often 16 or 21 mm.

It is necessary to choose a candle according to dimensions very carefully! The short part will not fully enter the engine socket, and the long part will protrude from it.

Replacement frequency

Different car models have different spark plug replacement intervals. It is always indicated by the manufacturer in the operating instructions for the vehicle.

Exists a number of signs indicating the need for replacement:

• increase in fuel consumption;
• vibration during engine operation;
• difficult engine start.

In most cases, replacement should be done every 20-30 thousand kilometers, on many foreign cars much later. Expensive iridium and platinum parts can easily withstand more than a hundred thousand miles.

Only the entire set of spark plugs should be changed! This will avoid unstable operation of the motor in the near future.

How to choose new candles

When choosing new spark plugs, you should first of all be guided by the recommendations of the vehicle manufacturer.

When choosing a new part, you need to rely on on the make and model of the machine, engine type, and also take into account the main technical characteristics of the part (discussed in the article above).

Difficulty in choosing new candles may arise due to the lack of a single marking of spare parts - each company has its own. However, the main characteristics of the element reflect all firms.

For the correct selection, you can use:

• manufacturer's candle catalog (on the brand's website, in an auto parts store or at a service station);
• numerous online resources for self-selection by car brand and its wine code.

Online recruiting services

For 15 years I have been repairing various types of cars, including brands such as VAZ, UAZ, Chevrolet, Mazda, Kia and many others. Everything related to the box, engine or chassis. You can write me your question below in the comments and I will try to answer it in detail.

In order for the fuel to burn correctly and fully in the engine, it is required to use an appropriate ignition source in the system. If we talk about engines that run on gasoline, then such a source is a spark plug. It is intended to ignite the fuel mixture by means of a discharge. It is important to responsibly approach the choice of candles, since the performance and service life of the motor depend on it. Our experts will always help with the right choice of candles.

Types of spark plugs

Spark plugs have been used in car construction for many decades. At the same time, they are continuously improved by manufacturers. For each type of engine, there are corresponding types of spark plugs:

1. For gasoline devices, spark devices are used.
2. For gas turbines, a surface discharge product is intended.
3. For turbojet manufacturers offer arc.
4. For a diesel engine, a carburetor engine, for those used in ship and aviation business, glow plugs are intended.

Spark plugs are the most popular, since they are suitable for gasoline units. They are necessary in order for the fuel in the cylinder to ignite. In turn, spark products are subdivided according to the type and number of electric conductors:

• with one electrode;
• with a large number of electrodes;
• torch;
• plasma prechamber.

What is a heat number?

The glow number is an indicator that the spark plug is capable of providing timely ignition and combustion of the fuel. Practice shows that if the candle does not heat up enough, then its service life is significantly reduced due to the formation of soot. In this case, the fuel cannot burn completely. There are also cases when the products are too hot, and then ignition can occur suddenly, not only from the incoming charge. Because of this, the motorist may experience burnout of the valves, their deformation. If we consider this parameter, then it is worth highlighting the varieties of products according to the magnitude of the glow number:

1. Hot, their value is from 11 to 14, this option is considered ideal for motors with a small afterburner.
2. The averages are from 17 to 19.
3. Cold equates to 20, intended for powerful motors.
4. There are also unified ones, their value varies from 11 to 20. They have a characteristic difference - such candles have a semi-open structure. Due to this design feature, the product does not clog.

What else to pay attention to?

Among the characteristics of products, their dimensions are noted, which must be taken into account when choosing. It is important to understand what size product is in the motor. If we talk about dimensions, then it is necessary to take into account such parameters as the metric thread on the body, the length of the threaded part, the size of the hexagon head. The gap between the electrodes of the candle also matters. Manufacturers set their own gap sizes, they depend on the technology of creation and the materials used.

The material also matters. So, alloy steel is used to create side electrodes. Such candles are distinguished by a long service life and quality. In most cases, nickel or copper is used to create the central electrodes. The use of these materials provides the ability to prevent carbon deposits, various pollution, and has a positive effect on the service life.

What candles to choose?

You need to be extremely careful when choosing, the operation of the car engine depends on it. The best solution is to trust the technical recommendations of the machine manufacturer. In the transport passport or instructions for use, you can find the appropriate recommendations. The manufacturer usually tells in detail which spark plugs are suitable for the car. So that motorists can easily select products, each has its own marking. For clarity, it is worth considering a standard marking example. We take a product marked AU17DVRM and try to figure out the meaning of its code.

• A - thread on the body M14x1.25 mm
• U - head size for hexagon 16 mm
• 17 - glow number
• D - length of the threaded part 19 mm
• B - the thermal cone of the insulator protrudes
• P - built-in resonator to reduce radio interference from the ignition system
• M - copper electrode

It is worth giving preference to products from trusted manufacturers. To date, there are many certified points where you can pick up original parts. Companies such as NGK, Denso, Bosh, Brisk are considered popular. It is worth talking about some of them in more detail:

1. Bosch. These products are famous for German quality, the products occupy a leading position in the market. They are used for cars such as Toyota, Mitsubishi, Fiat, Audi. The manufacturer offers motorists a huge selection, among which everyone can choose something suitable. Such products can work even when the battery is low, and are notable for their long service life and environmental friendliness. Many products of this manufacturer are considered universal, they can be combined with a large number of cars.
2. Denso. They are considered a more affordable option when compared with other manufacturers. But at the same time, among their advantages, one can distinguish a long service life, versatility of products, the ability to self-clean when working at high speeds. Such spark plugs are famous for their excellent quality characteristics. The market regularly sells such products in large volumes. At the same time, the organization involved in the creation of candles offers products to Ferrari, Volkswagen, BMW, Volvo.
3. NGK. This product also has a long service life, it can be used for 50 thousand kilometers. Regardless of what the battery charge is, stable operation is noted. Such products are quite expensive, but they are notable for the high resistance of the central electrode to damage.

Making the right choice

In order not to make a mistake with the choice, it is better to be guided by the recommendations given by the manufacturer of your machine. The instructions that come with the car always have detailed recommendations on this matter. It says which brand is installed at the factory and is the best solution for the system, since the manufacturer tries to take into account all the features of the model, in particular, the technical characteristics. If you wish, you can purchase expensive candles that are unlikely to be found in the manufacturer's recommendations. At the same time, it is worth considering whether such a purchase will justify itself? When choosing, you must take into account the average speed of your ride, and the type of fuel used. Is it worth it to buy expensive candles when the engine does not require extreme power? You should focus on the following parameters:

• life time;
• the temperature at which the product will be used;
• thermal range;
• marking.

Marking the product greatly simplifies the choice, but it must be borne in mind that at present there is no single marking standard, you need to know the decoding of the code of this particular manufacturer. Of course, this is not convenient, because for candles from different manufacturers, alphanumeric designations can be deciphered in completely different ways. Therefore, it is worthwhile to understand the code on the candle more carefully.

When should spark plugs be changed?

Not every motorist knows when it is time to change the spark plugs. Therefore, you should get acquainted with the main signs that the service life of the candles has already expired:

1. Turnovers began to gain much more slowly.
2. The power of the car is noticeably reduced, it is felt when driving.
3. Fuel consumption during wear increases significantly. This can also be observed with other malfunctions, but when the candles are worn out, this is one of the main indicators.
4. It is worth paying attention to the appearance of the product, it can tell whether the part is worn out or not.
5. The machine may simply not start, it may not start the first time. Problems when starting the engine directly indicate that it is time to replace the part.
6. Unstable operation of the motor may be observed, it may twitch during the trip, troit, so to speak. It can also work in waves, which will also be felt.
7. Due to the unstable operation of the motor, the corresponding vibrations are transmitted to the cabin.

Spark plugs for popular cars

When you realize that it's time to replace the products, you should start looking for a suitable option. Many motorists refuse to purchase the so-called heaped spark plugs. This applies to such budget cars as Hyundai, VAZ, Solaris, Logan. It also makes no sense to buy expensive products for drivers whose cars are under warranty. The fact is that the replacement of candles in this case is necessary for each passage of maintenance. Practice shows that, on average, a car manages to cover about 15 thousand kilometers during this time. Therefore, there is no point in purchasing expensive products.

More expensive candles promise a long service life, but if a replacement is required according to the regulations, then they will have to be changed. And an ordinary nickel candle easily passes 15 thousand kilometers, while it is recommended by the car manufacturer. Each manufacturer has models that are included in a number of budget ones. So, for Logan, if it is under warranty, you can pick up budget options BERU Ultra X UXF79, NGK BKR6E. Their cost is affordable, it will take about 150 rubles to purchase.

If the car is no longer under warranty, then you can give preference to more expensive options. Today, the market offers excellent products coated with precious metals. By giving preference to them, you can forget about problems with candles for a long time. Remember that when replacing products, the engine must be fully functional, as well as the fuel and air systems. The product manufacturer cannot guarantee stable and long-term operation if the system is defective.

Therefore, the best solution would be to make sure before buying that everything is in order with the machine. The system should work properly on good fuel. If you find any problems, then the best choice would be to deal with the technical part. Only after that it will be possible to change products for new ones. So you avoid wasted spending.

When making a purchase, remember that it is worth checking the spark plugs before you pay for them. Dirt on the electrodes, lack of marking, deformation of the components of the product can indicate a fake or a marriage. If you regularly carry out diagnostics, change candles in a timely manner, you can count on a long engine life.
