Which spark plugs to choose for the VAZ 2114 and how often should they be changed?

One of the most popular domestic cars. Built on the VAZ 2109 platform. Sporty appearance, good technical performance, excellent cornering, excellent weight control - these are its main characteristics.

Initially, the model was presented with a 1.5 liter 8 valve engine. Ten years ago, a car appeared with a 16-valve 1.6-liter engine and 77 horsepower. Two years later, the manufacturer increased the power to 89, in 2010 to 98. The transmission is 5-speed, fuel consumption in the city is 7 liters, on the highway - about 9 liters per 100 km.

The operation of an internal combustion engine depends on the air-fuel mixture and its ignition. The throttle, air filter and spark plugs are responsible for this. The latter lose their useful properties during operation and require replacement with new ones.

The device of spark plugs VAZ 2114

Products come in several types: classic (two-electrode) and multi-electrode. In addition, they are classified according to such criteria as: material of manufacture, size, heat rating (cold or hot). In addition, for a particular device there are standards regarding the size of the gap between the electrodes. In relation to the VAZ 2114, a classic design is used. Main components:

• side and central electrodes (responsible for generating a spark);
• frame;
• resistor;
• insulator;
• contact (to which the high-voltage wire is connected).

Keep in mind that spark plugs for the VAZ 2114 (injector) may not be suitable for cars of other brands and vice versa.

How to check spark on a spark plug

If you experience unstable engine operation, it begins to “triple”, it is quite possible that it is time to change the spark plugs, or the PVN, or the ignition module needs to be replaced. So, first, let's check the spark plugs of the VAZ 2114, most often the reason is in them.

• We remove the PVN tips from the spark plugs
• Unscrew all 4 spark plugs (you will need a 21 key)
• We put the tip on the spark plug and lean it against the metal (possibly against the body of the engine block)

Attention! The spark plug is under high voltage at this moment, so it is better to hold it with pliers or something similar

We start turning the starter and look at the spark plug, if there is a spark, then the spark plug is working. We do the same actions with other candles.

What candles should I put?

Choosing candles is a responsible matter. The service life of the engine, its power, fuel consumption, and successful starting depend on their quality.

When choosing, the greatest attention should be paid to the central electrode, such indicators as: heat resistance, thermal conductivity and ductility.

The best products are candles in which the smallest gap is 0.4 -0.8 mm, made of expensive materials: platinum, iridium, palladium coated with silver or gold (video author - Avtosferaomsk).

It is important to understand what kind of spark plugs are produced for the VAZ 2114. When choosing a new product, you need to study its characteristics in order to choose which spark plugs are better. A large number of SZ manufacturers have appeared on the car market, but there are several leaders whose products are in greatest demand. SZ must work synchronously, so you need to buy them from the same manufacturer and from the same material.

Domestic manufacturers include DVRM candles, produced in the city of Engels. They are installed on VAZs from the factory. The quality of the products corresponds to the price, but there are defects, so when purchasing they need to be checked for serviceability. Products A-17DVRM (1.0) are produced for engines with injector 8 and A-17DVRM (1.0) for 16 valves.

Domestic SZ A-17DVRM

Among imported products, good Czech Brisk candles. They are in demand due to their good quality. 10 series of these products are produced, differing in design. They have a clearance of 1.1, there is an SZ for 8 valve injection engines - BRISK SUPER FORTE LOR15YC-1 and for 16 valve BRISK SUPER FORTE DOR15YC-1.

Japanese products are always of high quality. These spark plugs are installed on some brands of cars directly at the factory. They have a higher price, but also have corresponding quality. When purchasing, you should beware of fakes, as there are a lot of them. For engines with 8 valves with an injector, DENSO W20TT is intended, for engines with 16 valves - DENSO W20EPR-U11.

NGK is a leading manufacturer of SZ. They are installed by manufacturers on some brands of foreign cars. As a car enthusiast, I claim that spark plugs last an average of 25-30 thousand kilometers. For engines with a 16-valve injector, NGK spark plugs No. 13 BPR6ES-11 are produced.

LADA spark plugs: top 10 options

The rating contains 10 modifications of spark plugs, without division into specific car models.

10th place: ZZ A17 DVRM

The list of the best offers opens with an effective model that is in demand among a large number of buyers. Such prevalence is ensured by the stable quality of products. In the original packaging it is impossible to find a defective part or a spark plug with a broken gap. A significant advantage of the products is the ability to work actively even when the voltage drops to 6V in the on-board network. Similar spark plugs in the VAZ 2107 are often found due to their moderate cost.

The indicators are overshadowed by bad statistics - as of 2020, 35% of the kits on the market are fakes, which forces motorists to carefully select products in stores.

Advantages:

• reasonable price;
• durable;
• simple design.

Flaws:

• plenty of fakes.

9th place: TZ 17 DVRM

The next representative of the rating implies the presence of as many as three electrodes on the working part of the device. A large number of motorists install such spark plugs on a VAZ carburetor or even an injection type. Thanks to the use of advanced developments in design, the manufacturer has increased the service life of the electrode.

Pirate copies also play a role here - there are a large number of them, which makes buyers cautious about purchasing products.

6th place: NGK BPR6 ES-11

The specified spark plugs for the Lada Granta are quite suitable. The model stands out among its competitors because it is manufactured in France. European quality did not suffer even with a fairly successful attempt to reduce the cost of products. The design and appearance of the part leaves much to be desired. Here you can find an unevenly soldered electrode or a damaged manufacturer’s logo.

On the other hand, the models work excellently for a long time and do not react significantly to piston wear - the spark plugs react normally even to oil getting on the working surface. A good and stable spark breaks through even on “smoky” electrodes.

Advantages:

• good performance on old and new engines;
• good quality at a reasonable price.

Flaws:

• a huge number of fakes.

5th place: BOSCH WR7DPX

Flaws:

• not detected.

Which spark plugs for VAZ are better to choose?

There are a large number of different modifications of the part, which complicates life for motorists. The problem is that each motor is designed for a specific type of spark plug. If you supply the wrong part, a number of negative consequences can arise.

1. Misfire of the mixture due to the gap between the electrodes of the element being too wide.
2. Interruptions in the operation of the internal combustion engine caused by too low spark power.
3. Instant failure of the device due to too much electrode protrusion.

In what cases is it necessary to replace spark plugs?

Replacement of SZ with VAZ 2115 and VAZ 214 is carried out every 30,000 thousand kilometers. If you do not change the SZ in time and continue to operate the car, then the wear of the electrodes sharply increases, this entails a drop in the car’s power and excessive fuel consumption. The condition of the spark plug and the ignition system as a whole can be determined based on the appearance of the electrode, the amount and color of carbon deposits on it. Brown soot is considered normal.

With long-term operation, the operating characteristics of the motor change. If you carefully monitor the operation of the internal combustion engine, then based on fuel consumption you can draw conclusions about the condition of the engine. Knowledgeable people recommend changing spark plugs on VAZs after 20 thousand kilometers, and in winter even after 15 thousand.

You can judge the need to replace SZ by their appearance, more precisely by the amount and color of carbon deposits, as well as the gap between the electrodes.

In addition, the dryness of the threads should be checked. If there are traces of oil on it, this indicates problems with the tightness of the system.

To summarize, we can cite cases when it is necessary to change the SZ:

• the car does not start well;
• fuel consumption has increased;
• the engine starts to stall;
• engine power decreases;
• exceeding the recommended mileage for replacement.

How to choose good candles

When choosing spark plugs for 2114 8 valve injector, you should be guided by the following important points:

1. Electrode homogeneity. A high-quality branded candle, even a budget-class one, will have electrodes with a clean, single-color surface. The presence of any stains on it should immediately cause refusal of the purchase.
2. Manufacturer. It is best to give preference to time-tested products. Thus, spark plugs from Finwhale, Champion, and Bosch Platin receive good reviews from car enthusiasts.
3. Color and size of electrodes. The highest quality candles have the thinnest electrodes (they are usually made of alloys of gold, silver, palladium, platinum or are coated with these metals). Spark plugs with the usual thick electrodes are more budget-friendly and have a shorter service life and lower-quality spark production.

One of the most objective methods of identifying a fake is to study its value. As already mentioned, the electrodes of good spark plugs contain rare earth or even precious metals, which makes their high price obvious. That is why you should not purchase such products, the cost of which does not differ from the cost of ordinary candles, because in the vast majority of cases they will turn out to be fake.

We choose which spark plugs are best for the 8-valve VAZ-2114: injector and spark plugs for it

In the ignition system of the VAZ-2114, spark plugs are in the leading place, because it depends on them how the engine starts after turning the ignition key. Therefore, it is to this detail, like no other, that much more attention should be paid during selection. And in this article we will tell you in detail about the design of the spark plug for the VAZ-2114, as well as how to choose the right one.

Rating of the TOP 5 best spark plugs for VAZ cars

Copper-nickel spark plugs for VAZ cars of the “Standard” category are used on carburetor engines with a contact ignition system; their reliable service life does not exceed 10,000 kilometers.

Attention! These are products with a good reputation, so they are massively counterfeited. The rules for identifying the original can be found on the manufacturers’ websites.

Spark plugs for VAZ 2113/2114/2115

VAZ 2113, 2114 and 2115 (Samara-2 series) are very similar in design, have a common platform and are equipped with the same engines - 1.5 (VAZ-2111, 77 hp) and 1.6 (VAZ-21114, 82 hp . or VAZ-11183, 81 hp).

Spark plugs for VAZ 2113/2114/2115 do not differ in any way depending on the configuration, year of manufacture of the car, or the installed engine. The same spark plugs are installed on all 3 cars. The original manufacturer is the Russian company “E3”, Engels. What is noteworthy is that the production facilities of this company belong to Bosch. Spark plugs for VAZ 2113, 2114, 2115 – which ones to install?

On VAZ 2113/2114/2115 with 1.5 and 1.6 liter engines, spark plugs should always be placed under article number 21110-3707010-86. It is also found under other numbers - 21110-3707010-00 or 2111-3707010. In fact, these are all the same spark plug. In the manufacturer's catalogs it has the article number A17DVRM. This spark plug has a central nickel electrode, single-contact, short thread, tightening torque - 22 Nm.

The dimensions of the original spark plug are shown below.

* according to Champion nomenclature (Russian standard)

Original candles, as a rule, are usually sold in branded packaging from LADA. Less often you can find them directly from the manufacturer - the Engels plant. They come from the manufacturer a little cheaper. The reviews from most drivers about this spare part are positive, and there are not too many fakes on the market, due to the fact that they do not have a very high price.

What analogues are there?

The most famous substitutes for the originals from other manufacturers are presented below.

In addition to conventional (nickel) analogues, more modern platinum or iridium spark plugs are also somewhat popular. They are installed to achieve a slight improvement in the dynamic characteristics of the engine. This is achieved thanks to a thinner electrode than nickel models. In addition, they last several times longer. For VAZ 2113, 2114 and 2115, the most popular are platinum Bosch 0242235540 at 200 rubles/piece, or iridium DENSO IW20TT, 610 rubles/piece.

When to change spark plugs on a VAZ 2113/2114/2115?

According to the maintenance regulations for VAZ 2115, 2114 and 2113, spark plugs must be changed every 30 thousand km. But, as the experience of drivers shows, this period needs to be reduced by half on average, and in fact, replacement needs to be done every 15 thousand km. This is influenced by many factors, the main ones being fuel quality and operating conditions.

DIY replacement instructions

Replacing spark plugs on VAZ 2114 and 2115 is not a complicated process. This work can be performed by any motorist, following the step-by-step instructions given below.

Tools and materials

To carry out the procedure you need to prepare:

• key for removing protection;
• a set of round probes;
• spark plug key;
• new set of SZ.

To avoid counterfeiting, you should purchase original products.

The process of dismantling and replacing SZ

Unscrewed from the SZ socket
The procedure for unscrewing and replacing spark plugs must be performed on a cooled engine to avoid burns.

The process itself consists of the following steps:

1. First you need to open the hood. Then you need to remove the protection from the engine, if present.
2. After removing the decorative trim, you need to remove the protective caps with high-voltage wires that are placed on the contacts. The caps should be removed carefully so as not to damage the wiring.
3. The areas near the NW should be cleared of dirt so that they do not get into the engine cylinders.
4. Now, using a spark plug wrench, you need to unscrew the S3 from the cylinder head. You can start twisting from any side. First you need to move it from the dead center, and then you can carefully unscrew the SZ from the socket.
5. Having turned out the old SZ, you need to wipe the thread with a rag.
6. Before screwing in new products, it is advisable to check the gap on each of them. For cars with an injector, it should be from 1 to 1.13 mm.
7. Installing the SZ is the same simple procedure as unscrewing; it is carried out in the reverse order. New products are placed in the seats of old candles. You need to screw it in carefully so as not to damage the threads in the cylinder head or on the product.
8. Next you need to put on the ends of the high-voltage wires. In this case, you need to make sure that the numbers of the wires that are printed on them match.
9. At the final stage, the decorative overlay is returned to its place.

After replacing the SZ, it is necessary to observe how the engine operates. If it works intermittently, it is possible that one of the SZ has defects. To detect it, you need to sequentially disconnect each high-voltage wire. A faulty spark plug should be replaced.

Price issue

High-quality products always cost more. Domestic products are several times cheaper, but the quality leaves much to be desired. Therefore, it is worth buying imported candles that will last much longer than domestic ones. At the same time, the service life of the engine will be extended, and fuel will be consumed more economically.

1. Czech SZ Brisk (price per set from 275 rub.)

2. Set SZ Denso (price from 121 rub.)

3. SZ company NGK (price from 180 rub.)

Spark plugs NGK No. 13 BPR6ES-11 for 8 valve injection engines. Cost 450-500 rubles per set

Before installing new spark plugs, you should check their functionality. This can be done using a special device, or on a stand.

Signs of faulty spark plugs

Malfunctions directly affect the operation of the internal combustion engine (misfire, engine tripping, failure of one or more cylinders and other problems). The most common signs that indicate a malfunction are: - disturbances in the operation of the ignition system (the car is difficult to start); — increased fuel consumption; — deterioration of the dynamic qualities of the internal combustion engine.

An important parameter that affects the operation of the product (the production of a proper spark) is the gap of the VAZ 2114 spark plugs between the side and central electrodes.
