Characteristic

The Japanese company NGK produces high-quality components for internal combustion engines and is one of the world leaders in this field. It is constantly engaged in new developments, improving its products, increasing their technical and operational characteristics, as well as increasing the service life of NGK spark plugs. Products are produced in a wide range. To choose the right NGK spark plugs, you need to know their main characteristics (author of the video - Tips for a car enthusiast).

Range

To improve the quality of products, the manufacturer NGK uses the latest high-quality materials using the latest technologies. The series consists of 7 types of candles with different parameters, each of them has its own characteristics. The series includes single-electrode products, modified by the company’s specialists.

Thanks to small changes, it was possible to achieve effective operation of the products. A notch in the shape of the letter V was applied to the central electrode. This made it possible to redistribute the potentials to the edges, where gasoline vapor is more concentrated. This ensures ignition.

When producing NGK multi-electrode spark plugs, the latest technologies are used, which ensure reliability through duplication. This guarantees the occurrence of a spark under any operating conditions. The number of side electrodes can be from 2 to 4. They are located evenly in a circle around the central electrode. Thanks to this design, the products are less clogged, and the service life of NGK spark plugs is also increased.

Products with a central cone-shaped electrode and soldering made of precious metals and rare earth metals are becoming increasingly popular.

Soldering is done on the side electrodes from the inside. Iridium and platinum are used as soldering. This extends the life of the spark plugs.

Standard single electrodes are used on many vehicles. The V-shaped notch made it possible to redistribute potentials to the edges, where a large amount of fuel vapor collects. This guarantees 100% ignition of the fuel assembly.
Multi-electrode products use the principle of duplication, which allows for stable spark formation, even if low-quality fuel is poured.
Elements with an additional spark gap are used for operation in conditions with increased soot.
With a semi-sliding surface discharge, they guarantee a cold start even if there is a lot of soot on the insulator. In this case, the soot burns at a temperature below the temperature at which self-cleaning occurs.
Hybrid ones combine a semi-sliding surface discharge and a platinum tip.
The middle electrode has an iridium tip. This is the strongest material that is resistant to spark erosion. The service life of iridium spark plugs is twice as long as that of conventional spark plugs.
Platinum products have a platinum solder on the electrode, which ensures constant power throughout the entire service life.
Spark plugs for racing cars can withstand increased loads, vibrations, high pressure, and elevated temperatures. The side electrode in the form of a ring prevents the spark from slipping; it goes to the central electrode.
NGK LPG LaserLine products are specially manufactured for power units running on gas. Thanks to platinum inserts on the electrodes and an iridium tip, the products are resistant to high gas combustion temperatures. A special coating protects the housing and copper core on the central electrode from overheating.

Advantages and disadvantages of products

Reviews about the spark plug, as well as about the NGK ignition coil, are mostly good, since NGK products are distinguished, first of all, by their high quality.

But besides this, there are a number of advantages that spark plugs br6hs, bpr6es, bpr7hs, bpmr7a and other models have:

Platinum and iridium products have an alumina ceramic insulator. It is an excellent dielectric with good thermal conductivity, and also has high strength;
the corrugated tip eliminates spark overlap;
high thermal conductivity, provide heat removal, protecting the spark plugs from overheating;
due to its high strength, the insulator will protect the product from damage during strong heating or cooling;
the design of the candles is sealed;
a high heat rating and a long service life of NGK spark plugs are ensured by a copper core, which has high thermal conductivity and low resistance;
have good resistance to soot;
High-quality cold-rolled thread makes it easier to unscrew the spark plugs.

Compared to analogues, NGK spark plugs have a long service life, high spark generation efficiency, durability and quality.

Marking

NGK spark plugs are supplied in separate packaging. To facilitate selection by vehicle, markings are applied to the product body.

To choose the right candle correctly, you need to know the decoding.

Below we will consider the decoding using the example of spark plug bcpfr6a - 11:

BC – thread diameter and key size (A - 1.8 cm, C - 1 cm, D - 1.2 cm, E - 0.8 cm, AB - 1.8 cm, BC and VC - 1.4 cm, DC - 1.2 cm);
P – type of spark plug (D – with increased reliability, I – iridium, L – with extended thread, P – platinum, S – platinum with increased reliability, Z – with a spark ring protruding along the edge of the skirt). These designations can be indicated in various combinations;
F – body dimensions used for unscrewing;
R – is there an interference suppression resistor;
5 - heat number (the value ranges from 2 to 13, the lower the number, the “hotter” the candle);
A - special characteristics;
11 – interelectrode gap.

Other characteristics are also possible that describe the feature of a particular spark plug: S – with a sealing washer, A – without a sealing washer, G – the presence of an additional side copper electrode, D – the body has an anti-corrosion coating and others.

The marking will simplify the selection of products for a specific car model from the NGK catalog (video author – StarsAutoCom).

Selection options

It is known that power units have different heating temperatures, so when selecting, you need to take into account the heat rating. For each vehicle it is indicated in the owner's manual. There are analogues that fully correspond to the originals installed at the manufacturing plant. The markings are on the body and packaging.

NGK spark plugs fully meet all standards and factory regulations of any car brand. For each engine, the spark plug is selected according to the marking.

There are special programs for decrypting it. They help you select products for your car. To go to the page where you can select a product, you need to select the catalog of interest. It is possible to select spark plugs for a specific make and model of car. Even a novice user can figure it out.

Original vs fake: how to tell the difference?

Due to the popularity of NGK products, many counterfeits have appeared on the market, which increases the risk of buying a counterfeit. In order not to purchase fake NGK spark plugs, you need to know the main differences between the original and the counterfeit, what you should pay attention to when purchasing. There are several features that can be detected by visual inspection:

Fake spark plug

The original box has high-quality sizing, the applied paint adheres well, the slots are made neatly and evenly. The marking is applied clearly, evenly and does not wear off over time.
The original insulator uses high-quality ceramics; there may be residues of ceramic powder on the metal body.
The central electrode is precisely located in the center, its rod should be copper. The sparking end of the insulator must be free of contamination. The side electrode must be smooth.
On the original, the threads are knurled, not cut. It should not be jagged or uneven.
The nut on the terminal is tightly screwed in; it takes a lot of effort to loosen it.
On a fake, the logo may be applied incorrectly.
The original hexagon must have a code on it.

Conventional spark plugs last 20-30 thousand kilometers, and iridium spark plugs last up to 100 thousand.

Detailed catalog of NGK candles

The Japanese company NGK, abbreviated in Russian as NZhK, is one of the leaders in the production of spark plugs. Their products are of high quality and also have a long candle life. Reviews from car enthusiasts indicate that NGK spark plugs, despite their design and modification, are excellent for any type of gasoline power unit. Therefore, the products of this company will be discussed below.

General characteristics

This manufacturer has been on the market for a long time, and is well known for developing spark plugs for power units of well-known automobile companies. Spark plugs from NGK undergo rigorous testing, so there are virtually no defective products in one batch.

Due to the fact that technical progress and developments do not stand still, today NGK candles have the following technical characteristics:

resistance to harmful environments, the working part of products that work directly in the combustion chamber are made of various metals and other materials that are resistant to high temperatures, loads, as well as the effects of harmful chemical compounds arising during the combustion of the fuel mixture;
great work resource, depending on what materials the electrodes are made of, the maximum service life of spark plugs can reach more than 160 thousand kilometers, and the minimum is 15,000;
low cost, even items made of precious metals do not have a high cost, so the products of this company are affordable for car enthusiasts with low incomes;
optimal heat number, it’s no secret that the ignition elements that are installed on modern power units contain such technical characteristics as a heat rating, and depending on it, the spark plugs are cold or hot, if the heat rating of the spark plug and the power unit do not match each other, then the motor may simply become unusable.

It is important to remember that there are analogues of such products that are produced by other companies under license from NGK. They are no different from the original ignition elements, but their quality and service life may be lower.

NGK product marking

Due to the fact that the company is engaged in the production of spark plugs for various types of power units, it has developed an individual classification of its products, which can be found on the company’s official websites or printed catalogs.

The marking of NGK spark plugs consists of Latin letters, as well as digital designations, the interpretation of which is given in the attached table:

In order to understand such markings, let’s consider products that have the following digital and letter designations - bpr6es.

The first letter B means that the product has a thread diameter and a hexagon with a diameter of 14 millimeters/20.8 millimeters.

The second letter P indicates that the spark plug has a protruding insulator, and the designation R indicates that the product has an interference suppression resistor.

The number 6 refers to potassium indicators; according to the given markings, such a spark plug refers to moderately hot ignition elements. The Latin marking E indicates that the thread length is 19 millimeters, and S indicates that the candle has a standard design.

Here is a description of a specific product that has a specific marking.

Therefore, having in hand the technical data of the power unit, the driver must make sure that the NGK BPR6ES spark plug has a standard design with moderate heat and is suitable for his power unit or whether he needs to choose another product.

Another thing you need to pay attention to is the tightening torque. It is determined by the force with which the spark plug must be screwed into the cylinder block so as not to break or unwind from strong vibration. Depends on the maximum engine speed, which are indicated in the technical documentation of the machine.

It is important to remember that when choosing these elements, you must pay attention to the part of the table where the heat number is indicated. If the technical documents of the engine indicate a certain heat rating, then the driver must remember that it is possible to choose a spark plug with a higher heat rating, but it is strictly forbidden to choose a spark plug with a lower heat rating.

Types of spark plugs produced by NGK

The products of this company are varied. Let's consider what it offers motorists.

The classification of its ignition elements is of two types:

the metal from which the electrodes are made;
number of side (bottom) electrodes.

Let's consider each option in more detail.

Today, the electrodes of this company are made of nickel-chrome alloy, as well as precious metals. The first option is a budget option, so it is available to any car enthusiast.

The second option is characterized by the fact that spark plugs with electrodes made of precious metals work longer, have a self-cleaning function, save fuel, and also increase engine power.

Of particular interest are products with platinum electrodes. Platinum spark plugs have a stated mileage of more than 50 thousand kilometers, are also resistant to high temperatures, and create a white spark (the most powerful spark), suitable for all types of engines, even those that run on gas.

Iridium spark plugs occupy a special place. They can last up to 160 thousand kilometers, save about 8% of fuel, and are suitable even for the most powerful (sports) engines. Their price is slightly higher, but taking into account fuel savings, the overpayment will be recouped after a few months of operation.

But the motor will always work like a clock.

Now let's move on to the question of the number of electrodes.

It must be said right away that standard ignition elements have one side (bottom) and top (central) electrodes. NGK has figured out how to increase the service life of its products, and for this the following technical innovations have been developed:

the presence of a cut in the form of the letter V on the side electrode (which divides its surface into two parts), this is done so that the resulting spark first tends to one half, and after it cokes (carbon deposits form), goes to the second half, doubling the service life;
equipping the working part with two, three or four side electrodes is also a technical trick, which is based on the fact that if one side electrode fails, the spark will look for another, so it will remain just as powerful.

This is the modification of NGK spark plugs.

Speaking about which spark plugs are best for a particular engine, we can say with confidence that this parameter completely depends on the technical data of the power unit itself.

NGK is a recognized leader in the production of ignition elements for gasoline power units. When choosing its products, you need to pay attention to its labeling, as well as the technical requirements for spark plugs established by the engine manufacturer.

Variety of NGK candles

History and modernity

Japanese company NGK Spark Plug Co., Ltd Today it is one of the leading enterprises that offer consumers high-quality parts for internal combustion engines. Like other Japanese-made products, NLC spark formers have earned the respect of motorists and remain in great demand. They are reliable, have excellent performance and a long service life.

The company began its work as a small workshop in the 19th year of the last century, and today it is a large production with its enterprises in different countries of the world. The company has accumulated vast experience in the design and development of automotive parts. At the same time, great attention is always paid to improving manufactured products and increasing their operational parameters.

The manufacturer is continuously working to increase the range of its products and improve their quality.

NGK spark plug range

The catalog of spark generators of this brand is very diverse - they are offered candles of various types and designs with different characteristics. And to make it easier for car owners to navigate, purchase spark plugs in full compliance with the stated requirements and not run into fakes (of which, by the way, there are quite a lot of them lately), we offer a brief overview of the products being manufactured. This will help you make the best choice based on the car brand and ensure high-quality operation of your car’s engine.

NGK products (V-Line series) are designed for the correct operation of modern engines with very lean fuel. These spark generators contribute to reliable spark formation, and therefore combustion, in the engine cylinder block.

The main feature of products of this type has become the highest reliability during operation under various modes, regardless of the quality of the fuel assembly.

NGK spark plugs

Main range of SZ NGK

To improve the quality of products, high-quality materials are used in production and innovative technologies are applied. The V-Line series includes 9 types of candles with different parameters. Each type has its own characteristics.

The series features products having one electrode, which are brought to perfection by the best developers of the company. Making minor changes allowed the spark plugs to function more efficiently. A notch in the shape of the letter V was applied to the electrode (central). Because of this, the potentials are redistributed to the edges, at which the concentration of vapors of the working mixture is much higher. This creates a spark.

Production of SZ with several electrodes Based on duplication, this actually increases reliability. This ensures spark formation under various operating conditions. The number of electrodes on the sides depends on the type of SZ and ranges from two to four. They are located around the electrode in the central part. Spark plugs of this design are less clogged and have a longer working life.

Elements with a cone-shaped key electrode tipped with rare and precious metals are becoming increasingly popular.

Soldering is done on electrodes located on the side. For soldering, iridium or platinum is used - these metals increase the period of correct operation of spark generators.

Types of NGK spark plugs

As mentioned above, in the nomenclature list of manufactured products there are 9 types of spark plugs:

Standard ignition elements with one electrode. Great for cars of various makes and models. The notch in the shape of the letter V promotes the redistribution of potentials to the edges. This ensures uninterrupted combustion of the working mixture.
More complex multielectrode products are created using the duplication principle. This ensures stable sparking, even when refueling with insufficient quality fuel.
Spark generators that have an additional spark gap are designed for use in high soot environments.
Plugs with a semi-sliding surface discharge promote cold starting even if a large amount of soot has accumulated on the insulator.
The hybrid spark generator combines a semi-sliding surface discharge and a platinum tip.
NGK iridium spark plugs. Iridium is a very durable type of material that is highly resistant to erosion from spark formation. The working life of such ignition elements is 2 times greater than that of simpler modifications.
Elements with platinum soldering on the electrodes have constant power throughout the entire intended period of operation.
Special protective gear for sports/racing cars can withstand high loads, pressure and temperature. Thanks to the ring-shaped side electrodes, the spark does not break through, but is supplied to the main electrode.
SZ marked NGK LPG LaserLine are manufactured exclusively for engines that run on gas. The design feature of such products is the presence of platinum inserts on the electrodes, as well as an iridium tip. This makes the candle resistant to elevated temperatures when burning gas. The special coating protects the housing/copper core on the main electrode from overheating.

SZ marking and decoding

NGK elements are individually packaged and their identification is made by marking, printed on the body. Knowing this makes it much easier to choose a car brand. Let's decipher the marking using a specific example as a basis:

PFR5A-11

The letter (P) indicates the type of product: D - high reliability, I - spark plug with iridium, L - extended thread, P - platinum soldering, S - product with high reliability platinum, Z - spark plugs with a protruding spark ring located on the skirt. Letter designations are often combined in various combinations.
The letter symbol (F) is a characteristic of the thread and the key required for screwing in/unscrewing.
Symbol (R) – presence/absence of a resistor that suppresses interference.
A digital symbol, in this case 5, is the heat indicator (2-13, the “hotness” of the candles is determined from high to low - 2 indicates the highest indicator).
Letter symbol (A) - indicates design features;
Number (11) is the value of the gap between the electrodes (7 - 0.7mm, 9 - 0.9mm, 10 - 1.0mm, 11 - 1.1mm, 13 - 1.3mm, 14 -1.4mm, 15 -1.5mm).

NGK spark plug device

Additional parameters of certain features of the SZ can be added to the indicated symbols in the markings. For example: A - product without o-ring; D – body with anti-corrosion treatment; G – product with additional side copper electrodes; H – special thread and others.

What is important to know about SZ NGK

The original or a fake?

Since products manufactured by NGK are in high demand, Lately a lot of fakes have appeared on the market. Let's look at how to recognize the original and distinguish it from fakes:

The packaging of the original products has high-quality sizing, the paint does not rub off, and the edges of the slots are neat and evenly cut. Clear markings are easy to read.
High quality ceramics are used as an insulator in original products.
The main electrode is located exactly in the center and has a copper rod. There is no contamination on the spark-producing insulator. The electrode is smooth on the side.
The original has a knurled rather than threaded thread. The presence of jags and irregularities on it indicates a fake.
The nut on the terminal is screwed on very tightly. You can loosen it by applying sufficient force.
The logo on a counterfeit product usually has errors.
A code is applied to the hexagon of the original product.

Original and fake

It is very easy to distinguish a counterfeit from the original NGK ignition elements - you just need to look carefully at some basic features.

Service life and cost

Effective lifespan of NGK ignition elements may vary and depend on the specific modification. For products in the “regular” version, it is approximately 20 thousand kilometers. In turn, iridium products will easily ship 80 thousand. The service life is affected by the conditions in which the products are operated, the quality of the working mixture, climatic conditions, etc. It is necessary to periodically check the condition of the SZ in order to replace them in a timely manner.

When buying NGK products, don’t think about saving money, giving preference to cheaper options. So you can run into a fake that will not last long or with minimal efficiency.
