VAZ cars are quite in demand in the domestic auto market. Spark plugs can be attributed to consumables, but the reliable operation of the engine depends on their quality. The choice is based on the recommendations of the car manufacturer, since for each type of engine there is a certain list of parameters that candles must comply with.
Which spark plugs are best for VAZ
If you take a car of the 10th family or Priora, then you need recommended spark plugs for 16-valve engines, which have several differences from classic spark plugs for 8-valve engines.
Candle manufacturers
In the domestic market, you can find many candles from different manufacturers. The highest quality candles are produced under the following brands:
- Valeo;
- Bosch;
- Brisk;
These manufacturers are taking various approaches to improve the quality of engine performance. An important role is played not only by the material of the electrodes of the spark plugs, but also by the accuracy of manufacturing, in particular, the size of the spark gap.
Which spark plugs are better for Priora
The powerful 16-valve Priora engine requires the installation of high-quality spark plugs to reach its full potential. High-quality candles not only help to reduce fuel consumption, but also increase engine power by improving the ignition process of the fuel. NGK spark plugs have proven themselves well, which are designed in such a way that they are capable of self-cleaning. Therefore, their rather high cost pays off with an increased service life.
A significant drawback is the huge number of fakes ..
Low cost and good workmanship make these candles a viable alternative to expensive imported candles. In addition, they are practically not faked.
Spark plugs are not only the most important technical element on which the operation of an automobile engine directly depends, but also an excellent diagnostic tool. The condition of the spark plugs is the main indicator of engine performance, the quality of the fuel used, as well as the entire ignition system as a whole. As a rule, A17DV candles are used in VAZ 2107 cars with a contact ignition system and a carburetor, however, candles from manufacturers such as Bosh, Brisk, Champion, NGK are also suitable. For a contactless system, spark plugs A17DV-10 can be used.
Car engine diagnostics using spark plugs
As you know, spark plugs are the simplest and most effective tool for diagnosing engine operation. It is best to check the ignition system after a short run (on a hot engine). If the ignition system is set up in accordance with all operating rules, the unscrewed candles should have a slight light brown coating, and the electrodes should be intact and clean.
Why does he throw spark plugs on the VAZ 2107 injector?
As a rule, the cause of this problem is one. At low temperatures, oxygen requires more fuel, which instructs the injectors to increase the supply of gasoline. The nozzles cope with this task conscientiously and supply fuel to the combustion chamber, after which the starter creates sufficiently strong compression in the cylinders, while simultaneously supplying a spark to produce a flash. As a consequence, under compression conditions, the spark plugs start at a low pulse. Considering that perfect compression only happens in a new engine, it is the main reason for flooding the injector spark plugs.
If you want the VAZ 2107 engine to start normally in the winter season, and the spark plugs are not flooded with fuel, you need to “drive” a distance of 50-100 km at least once a month at a speed of up to 120 km / h. It is advisable to do this on good gasoline.
Checking the spark on candles VAZ 2107 injector
If the fuel pump in the tank works properly, but the engine does not start, then there is a problem in the ignition system. First of all, you need to check the spark discharge. To check the spark discharge on high-voltage wires, a spark gap is used. In this case, the use of a spark gap is mandatory, since the VAZ 2107 injection engines use the technology of static ignition distribution with the simultaneous supply of high voltage to two candles.
Other engine problems that can be identified when diagnosing:
- electrodes covered with tar soot indicate an over-enriched fuel mixture and incorrect operation of the carburetor;
- white coating on the electrodes - too poor fuel mixture;
- burnt electrodes - a clear sign of incorrectly selected spark plugs, or the use of low-quality gasoline;
- the oiliness of the electrodes indicates a malfunction of the piston group.
How to replace candles with a VAZ 2107 injector?
On a properly working VAZ 2107 engine, spark plugs can last more than 30,000 km. However, it is recommended to check the spark plugs after every 10,000 km and, if necessary, clean them.
In the process of checking and replacing spark plugs, you should be very careful and accurate: before unscrewing the spark plug, you need to clean the seats. This will prevent dirt from entering the engine cylinders. Also, do not apply excessive force, as a large load on the cylinder block can damage them.
As for the resource, the picture here is quite simple - at first the spark works with one contact which has minimal resistance, then as it wears out, the resistance begins to grow, so the spark goes to another contact and continues to work steadily smoothly. Thus, the resource, as practice shows, can increase two to three times. On some cars, such options go for 100 - 120,000 kilometers.
YES, and the formation of caviar is a little different here, look at the pictures.
The only weak link is the central electrode, it also wears out and as it wears out, the candle starts to work worse.
My review
Unfortunately, I don't have photos and videos of material from testing such candles. But I had experience. For a working VAZ 2111, multi-electrode options (three contacts) were purchased from BRISK, the name is if EXTRA memory serves me right. The issue price is about 180 - 200 rubles - a piece, they did not buy expensive NGKs, for our old working VAZ, this is too much. The car moved with them for about 40,000 kilometers, then it was taken by another unit and I could not track it. According to the driver, starting in cold weather has improved (not even on a new battery), throttle response has slightly increased, consumption has fallen, slightly, but it has fallen - according to the on-board computer, this figure is about 0.3 - 0.4 liters, which is about 4% savings. After 20,000 kilometers, we unscrewed a couple of pieces and looked at what happened to them and, you know, everything was in order, I know the mileage is small, but the first impressions have already been formed. Therefore, they really have an effect. Also watch the video I shot just for you, I found a worn version from BERU.
Test
ON the Internet, I have accumulated information about testing multi-electrode candles, I want to offer you the best five.
Manufacturer - FRANCE. By far the best of all. Issue price - 600 - 700 rubles a piece.
Structure - 4 electrodes, paired with different gaps to the central contact, two electrodes - 0.8 mm, two more 1.2 mm. Thus, suitable for many cars, whether it is a carburetor or an injector.
After testing: engine power increased by 3.7%, consumption fell by 4.2%, toxicity by 4.5%
Manufacturer - JAPAN. They take second place, slightly inferior to BERU, the issue price is 500 - 550 rubles / piece.
Three electrodes that have the same gap of about 1.1mm making them the preferred choice for injector applications. Sufficiently high quality, inferior only in fuel economy - here only 3.9%, but the rest of the characteristics are almost the same power - 3.7%, toxicity - 4.5%
Manufacturer - EUROPE. Third place, issue price 400 - 450 rubles / piece.
Three pins, about 1.1mm gap. Made with high quality, consumption fell by 3.5%, power increased by 3.4%, toxicity decreased by 4.0%
Manufacturer - CZECH REPUBLIC, 4th place, price about 700 rubles / piece.
We used a new technology in the structure, where the side 4 electrodes are lowered lower than the central one. That is, the spark, as it were, “slides” over the insulator, as it seems to me, because of this, the resource will be slightly reduced, however, in our test, it ranks fourth in terms of consumption (decrease - 3.1%), increase in power - 3.0%, toxicity (3.5% reduction)
An article about spark plugs for a car engine - varieties, selection criteria. At the end of the article - an interesting video on how to clean candles from soot.
The content of the article:
Engine operation largely depends on spark plugs, and the performance of the latter depends on the manufacturer and manufacturing technology. The spark plug rating is most often headed by recognized market leaders like Bosch, Denso, Beru and some others. These companies supply their products to automakers, so they strictly monitor the quality and adherence to technology.
Spark plugs - varieties and features
When choosing, the material from which the electrodes are made, as well as their number, is of primary importance.
According to the number of spark generators, spark plugs are divided into two-electrode and multi-electrode (plus plasma-prechamber, which is a novelty on the market).
Two-electrode
They have a main (central) and side electrodes. Candles of this type are a classic variety. When starting, a spark is formed between the electrodes, which ignites the fuel mixture.
Multielectrode
In addition to the central one, they have two or more side spark generators. The principle of operation is the same, but the design allows you to stabilize the formation of a spark and the operation of the propulsion system.
Plasma prechamber
Such candles appeared on the auto parts market around 2000 and still provoke discussions. Neither experts nor ordinary motorists have come to a consensus on what this new product is - either the next step towards increasing efficiency, or a futile attempt at improvement.
Pre-chamber candles differ from traditional ones in that the role of the side electrode is performed by the body of the product, equipped with a special heat-resistant nozzle. It is with its help that a spark is formed.
But despite this improvement, the best spark plugs, according to consumer ratings and reviews, are still traditional electrode ones.
Classification by electrode material
copper/nickel
The main characteristics of spark plugs are quality and budget. Of course, in terms of operating parameters, the products are far from those that will be discussed below, but for their price segment they have decent readings. On average, a copper-electrode spark plug is enough for 20 - 30 thousand kilometers, after which replacement is required.
Platinum (sometimes made from other precious metals)
The electrodes of the products have a platinum coating, due to which their service life is increased and the quality is improved. Such a candle is designed for a run of 50 thousand km.
iridium
The resource is up to 100 thousand km, and the quality indicators are many times better than the previous options. But the cost of the product is corresponding.
Rating of the best spark plugs
The market leaders have been determined for a long time. The results of tests, consumer votes, expert opinions sometimes differ, but the top positions in the ratings are almost always occupied by the same brands.

Which spark plugs are best for a gas engine
The peculiarity of gas is that its combustion temperature is slightly higher. This provokes intensive formation of carbon deposits and the appearance of oxides on the electrodes. Therefore, for gas-powered vehicles, it is recommended to install products with platinum or iridium spark generators.
When used on machines with LPG, good results were shown by:
- Denso Iridium IW20;
- NGK LPG Laser LineN2;
- Bosch Platinum WR7DP.
Conclusion
The most important thing when choosing spark plugs for the engine is not to get a fake. Handicraft enterprises throw on the market a huge amount of counterfeit products of the lowest quality. Therefore, when buying candles, you should pay attention to the reputation of the outlet, as well as check the part and packaging for belonging to the original.
Video on how to clean spark plugs from soot:
In the ignition circuit of the VAZ 2114, candles play a central role. In fact, it is the spark plugs that carry out the control signal that comes from the ignition key when it is turned to the start position. Having received a signal of 24 kV, the candles generate a spark and ignite the fuel injected into the combustion chamber. Therefore, vehicle drivers pay a lot of attention to them. In order to choose the right SZ, you need to know the features of their design.
Spark plugs on the VAZ 2114 are structurally no different from the SZ used in the ignition systems of other cars. The main elements of this device are:
- the body is made of metal, on the outside it has a hexagonal head for a candle key and a threaded part for screwing into the cylinder head housing, this part perceives 67 percent of the heat generated when the candle fires and gives off 91 percent of this heat to the block head housing;
- an insulator made of corundum ceramic with the addition of aluminum oxide, as well as oxides of other rare metals. It is inserted into a metal case;
- thermal cone, often referred to as the thermal cone skirt. In fact, this is the lower part of the insulator, it perceives 21 percent of the heat released at the time of sparking;
- a plug head is attached in the upper part of the insulator, inside it is a contact rod associated with the head, and in the lower part there is a central electrode;
- on the lower part of the candle body there is a side electrode, which is located above the protruding part of the central electrode, forming a gap for the formation of a spark;
- the thrust part of the housing is flat; for better tightness, a sealing washer is placed on it when installed;
- to form the strength and tightness of the joints inside the structure, there are ring seals and a heat-conducting glass sealant;
- to combat radio interference arising from sparking, an interference suppression resistor can be installed between the contact head and the central electrode.
All the constituent elements of the candle on the VAZ 2114 play an important role, but special attention is paid to the central electrode. It must have properties such as heat resistance, high thermal conductivity, ductility and high corrosion erosion resistance. To do this, it is usually made from various nickel alloys. However, in recent years, in order to improve the efficiency of the candle and obtain any unique properties during its operation, this electrode began to be produced from metals such as copper, iridium, palladium, as well as with platinum fusion and silver or gold plating.
How to choose spark plugs for VAZ 2114
The issue of choosing SZ if it is necessary to replace them must be taken seriously. Fuel consumption and engine power depend on how efficiently they work. When deciding which spark plugs are better for the VAZ 2114, the driver must be aware of which of the tasks they should perform. Tests carried out by specialists show that properly selected spark plugs for a particular engine can not only improve its performance, but also extend its life. It is not for nothing that special spark plugs with gold-plated copper electrodes are made for the forced engines of sports cars.
- The instruction manual for the VAZ 2114 indicates how much to change the spark plugs on the VAZ 2114. This is 30 thousand kilometers of the car. Of course, good, real factory candles can last 50 and 70 thousand kilometers. But this does not mean that if there are no problems with the launch and during the movement, then the candles can not be changed. In fact, as the electrodes wear out, the characteristics of the internal combustion engine change, and with careful monitoring, this is easy to detect by the changed indicators in fuel consumption.
- Specialists and experienced drivers strongly recommend changing spark plugs at least every 20,000 km, and in winter, after 10,000 km. Wherein it is necessary to constantly monitor the operation of the SZ and the gap between the electrodes. On the unscrewed candle, its condition will immediately be visible by the color of soot on the electrodes. It is also required to check the dryness of the threaded connection. The presence of fuel or oil on it indicates a lack of tightness in the system.
- The choice of SZ in auto parts stores today is quite large, and in order to decide which candles to put on the VAZ 2114, you need to study the technical characteristics of all the models offered. On forums and in automotive magazines, spark plugs with the brands NGK, Finwhale, Champion, Brisk Premium, Bosch Platin are recommended for the VAZ 2114. For example, when passing test tests, these kits, when compared with the Russian A17DMRV from Engels, showed 5-6% better power and 3.5-4.5% better fuel consumption. Despite the fact that foreign candle sets are much more expensive than domestic ones, they pay for themselves in half a year by reducing fuel consumption.
- The advantages of imported candles are best seen when they are checked on a special engine stand with photographing the sparking process. A simple single-electrode candle with a nickel electrode gives an intermittent multi-colored, randomly flying in different directions, spark. Candles from imported sets, when sparking, create a continuous cone of white fire.
- By the color of the spark, auto electricians determine the efficiency of a candle kit. If the color is red, then the spark is weak intermittent. Blue or cyan means a more intense spark. White fire means a spark that is intense and steady. It is this kind of fire that gives intense ignition of the fuel-air mixture during injection. This means better combustion, higher engine power and lower fuel consumption.
- The best spark is given by candles with the thinnest electrodes, 0.4-0.6 mm thick. Such electrodes are made of iridium, palladium or alloys with platinum and gold. Significantly improves the "spark" by sputtering silver, gold or platinum on the central and side electrodes. The thickness of the A17 spark plug electrode from Engels is 2.5 mm. Therefore, it cannot compete with expensive imported candle sets.
It is easiest to identify a fake at the selling price. As a rule, such "products" are sold for half the real cost of the "original". This should immediately alert the buyer. You should also check the candle itself before installation. On fakes, you can often find a rocking plug head.
When choosing candles for the VAZ 2114, it is necessary that quite often counterfeit products are found in our distribution network, that is, “home-made products” under well-known and expensive brands. If you accidentally install such candles on a car, then it’s good if you calmly drive one thousand kilometers on it.
