Which spark plugs are better for VAZ-2112 injector 16 valves

VAZ 2110/2111/2112 cars are the tenth series of domestic cars produced since 1995. Such cars were produced only with gasoline engines (injector and carburetor). Spark plugs for each car of the tenth family come with different part numbers, but in fact they are very similar in size and parameters. The differences in spark plugs on these three cars are due to different engines, although all of them are developed on the basis of a 1.5-liter 8-valve carburetor engine from a dozen.

Which candles to choose

For the VAZ-2112 there are many different brands of spark plugs, which differ in type, composition and appearance. Therefore, what exactly to choose is up to you, and below we will tell you about each of those that are most often chosen by the owners of “two-wheelers.”

• JSC ZAZS, Russia AU17DVRM
• BERU, Germany 14FR-7DU
• CHAMPION, England RC9YC
• NGK, Japan BCPR6ES-11
• DENSO, Japan Q20TT
• BRISK, Czech Republic DR15YC
• BOSCH, Germany FR7DCU
• FINWHALE, Germany F516

Standard spark plugs that are supplied with all VAZ cars from the factory. Despite the fact that the manufacturer recommends replacing only this model of spark plugs, many car enthusiasts do not share this opinion and use other brands.

BERU 14FR-7DU spark plugs have a special modification in the form of a copper central electrode with a nickel shell. This design increases resistance to wear and corrosion. The conical shape of the skirt allows you to very quickly switch to self-cleaning mode, which has a beneficial effect when traveling short distances in the city. Thanks to the increased spark power, the fuel burns most efficiently to the maximum - and this is already tuning the ignition system and engine.

Champion

Spark plugs from Champion. Made in the EU, Champion RC9YC spark plugs offer low fuel consumption, high stability and increased power at high engine speeds.

Japanese candles NGK BCPR6ES-11 are among the most affordable on the market in the price category.

An engine with such spark plugs runs very stable, and with the throttle valve open to full, it can develop 4.5% more power than with standard spark plugs. When tested on a stand, it shows a result in fuel consumption that is 3.9% less than the “stock” figure.

Denso

Spark plugs from Denso.

DENSO Q20TT has a thin electrode made not from precious metals, which primarily has a beneficial effect on its cost. Thanks to this spark plug shape, the engine experiences a steady increase in power, acceleration and dynamics come to life, as well as a reduction in fuel consumption.

Many owners of the VAZ-2112 note the smoothest and most stable operation of the engine at idle speed.

Brisk

Brisk DR15YC made in the Czech Republic, has a copper core and an extended central electrode insulator. The latter allows it to quickly switch to self-cleaning mode, so this spark plug is well suited for cars operated in urban environments. The interval for replacing spark plugs directly depends on the type and quality of fuel used.

Bosch

Spark plug from Bosch.

Bosch FR7DCU have a copper core in their design, placed in a chromium-nickel shell, which increases the electrode's resistance to corrosion and erosion. Nickel coating prevents sticking of threads and protects the spark plug body from the harmful effects of aggressive environments. The spark plug from this company showed stable, average results in terms of fuel consumption and acceleration dynamics.

Finwhale

Spark plug from FINWHALE.

The body of the Finwhale F516 spark plug is galvanized and made of highly ductile steel, equipped with high electrical insulation, due to which heat, conductivity and mechanical strength are increased due to the high content of aluminum oxide on the insulator. To ensure that the electrodes burn out less, they are made of a nickel alloy.

When to change spark plugs?

Such malfunctions include: engine “crackling”, increased fuel consumption, difficult starting, and so on. The condition of the candles can be determined by visual inspection of the central part of the candle or its body. The presence of soot, dirt and various cracks will directly indicate the need to replace it.

To make it easier for you to determine the condition of your candles by visible signs, we bring to your attention a special table.

Spark plugs VAZ 2110/2111/2112

404 11 403k

VAZ 2110/2111/2112 cars are the tenth series of domestic cars produced since 1995. Such cars were produced only with gasoline engines (injector and carburetor).

Spark plugs for each car of the tenth family come with different part numbers, but in fact they are very similar in size and parameters. The differences in spark plugs on these three cars are due to different engines, although all of them are developed on the basis of a 1.5-liter 8-valve carburetor engine from a dozen.

The VAZ subsidiary Lada Image supplies original spark plugs to the assembly line. The original spare part is sold in Lada branded packaging. But the manufacturer is the domestic company OJSC ZAZS, Engels.

Spark plugs for VAZ 2110, 2111, 2112 – which ones to put on the injector and carburetor

The spark plugs on the VAZ 2110/2111/2112 have a nickel central electrode, single-pin. For the VAZ 2110 the base engine is an 8-valve carburetor, for the 2111 it is also an 8-valve engine, but with an injector, and for the VAZ 2112 it is a 16-valve, injection engine. But in fact, each car was equipped with all these engines and their modifications. Therefore, spark plugs differ in the context of the 3 main base engines.

On each engine, the spark plugs have different markings, but for an 8-valve engine with an injector and carburetor they are the same and differ only in the size of the gap. Therefore, they can be interchanged by first setting the required gap. For VAZ carburetor engines, it is recommended to set it somewhere within 0.7 mm, but on injectors - 1 mm.

16-valve power units already have spark plugs that are slightly different from the previous ones. Therefore, it is not recommended to install them on 8-valve engines.

The dimensions and article numbers of the original candles are presented in the table below.

*according to Champion nomenclature

In fact, under the article numbers 21080-3707010-86 and 21110-3707010-86, which go to 8-valve valves, there is the same model of spark plug, only with a different gap. Directly from the manufacturer, it has the article number A17DVRM, the average price is 140 rubles/piece. And under the article number 2112-3707010-01 (for 16 valves) there is a spark plug AU17DVRM, the average price is 200 rubles/piece.

The most commonly used substitutes are listed below. Ten and eleven have the same analogues, only before installation it is recommended to check the gap and, if necessary, set it to the recommended values.

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.

• reasonable price;
• durable;
• simple design.

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.

• good performance;
• long period of operation;
• wide use.

8th place: DENSO W20EPR-U11

If you want to buy VAZ injector spark plugs, you can turn to the eighth position of the rating. Candles represent a compromise between high quality and moderate cost. Thanks to this symbiosis, such spark plugs are perfect for the VAZ 2106. Also, this model will be relevant for more modern versions. It uses technology to increase spark stability. The development significantly increases the service life of the part, which helps save on vehicle servicing. This also made it possible to reduce the maximum voltage drop to 6.5 V, which is less than that of Russian analogues, but thanks to stability, the spark plugs win positions.

• stable operation during voltage fluctuations in the on-board network;
• long service life.

Replacing spark plugs yourself

Before you start replacing old spark plugs, decide on the choice of new ones, you can read about this in this article. Also, before starting dismantling, make sure to place the car on a flat surface and disconnect the negative cable from the battery.

Required Tools

To ensure that the work of replacing spark plugs does not cause inconvenience, prepare all the necessary tools in advance:

Please note that the spark plug wrench must have a rubber seal, or it must be magnetized, to most effectively hold the spark plug while removing it from the well.

Step by step order

1. First, remove the plastic engine casing located on top.

If the bolts are not corroded, they will come out easily.

When the bolts are unscrewed, move them to the side.

This is what a spark plug key looks like

The key is in the spark plug well

When the spark plug is unscrewed

1. When your spark plug is unscrewed, you need to remove it from the cylinder head, but if this cannot be done with a key, due to wear on the O-ring, you can always take the previously removed ignition coil. Put it on the candle and remove it from the well.
2. Using the dismantled spark plug, evaluate its condition according to the table above, draw a conclusion about the operating condition of the engine, and you can begin installing a new spark plug.

When to change spark plugs on a 16-valve VAZ-2112?

Each spark plug manufacturer has its own schedule for periodically replacing spark plugs. However, the service life of 20-30 thousand kilometers for cars of the VAZ family is generally similar. However, if any interruptions occur during engine operation, as well as other reasons why it is necessary to replace the spark plugs, it is recommended not to delay and carry them out.

What to choose?

Frequency of replacing spark plugs in VAZ 2112

None of you have had this problem. Thousands of car owners around the world, remembering the wear and tear of the mechanical parts of the car, forget that even parts of the ignition system do not last forever. The operation of these electronic mechanisms is almost invisible to the driver and is taken for granted.

However, the spark plugs need to be replaced. The frequency of replacement depends on the design of the plugs and the material from which the central electrode is made.

Replacement of spark plugs on a 16-valve VAZ 2112 engine is carried out every 20-30 thousand km, if we are talking about standard spark plugs with conventional iron-nickel electrodes. Multi-electrode spark plugs are less susceptible to overheating and electrical erosion, which increases their service life. The most modern and expensive spark plugs with iridium and platinum electrodes can operate without replacement for 5-6 years and withstand 100 thousand kilometers.

Imagine this is where you fell. Remember that iridium spark plugs were replaced over seven years ago. During this time, you can forget a lot.

By carefully inspecting the part you are holding, you will notice obvious signs of wear:

• carbon deposits or deposits on electrodes and insulation. When the air-fuel mixture burns properly, the electrodes clean themselves. The nature of the problem can be determined by the structure and color of the plate: – red or brown color means that the fuel poured into the car is of poor quality; – light and whitish soot – lack of fuel in the combustion chamber; – a thin layer of carbon black – the air-fuel mixture is depleted of oxygen. The cause may be a dirty air filter; – a thick layer of black wet deposit means that the spark plug is filled with oil (smells like an engine overhaul!);
• insulation damage. The ceramic insulation is covered in cracks. This leads to random deep detonation of the air-fuel mixture, regardless of temperature.
• The “skirt” on the electrode is brown. The formation of a gap between the metal body of the spark plug and the ceramic insulator leads to combustion products entering there;
• greater distance between the central and side electrodes. This can be corrected by bending the electrode to the desired level. The size of the gap in millimeters is indicated in the marking of the part - this is its last digit. The absence of a number indicates an indentation of 8 mm;

Realizing that you cannot help but replace the spark plug, you begin to delve into your memory, trying to remember if there have been any indirect signs of a malfunction in the car recently:

• Multiple increase in fuel consumption (“Indeed, the old lady has been eating a lot lately...”);
• Stopping the engine at high speeds (“That’s it!”).
• Heavy engine operation, reminiscent of detonation (“I didn’t pay much attention to it”);
• Difficulty starting the engine and its unstable operation (you probably thought that the problem was in the oil, right?);

Cursing yourself for your carelessness and carelessness, you are already mentally preparing to explain to your family that you will be staying indefinitely... And then you remember that in the glove compartment you have a set of brand new candles, specially purchased last year in case of such a problem!

Spark plugs for VAZ (Lada) 2110/2111/2112

for repair of VAZ (Lada) 2110/2111/2112

I bought candles from what I had. In the end I bought Finwhale and changed it myself without any problems. At first glance, everything was fine, the car was driving normally, but after 5000 km, the engine began to misfire. I immediately suspected the candles and decided to install the original. On the original, all the problems disappeared. As a result, Finwhale candles have a very low service life and quality.

They recommended good Finwhale candles at a reasonable price, I bought them, installed them, they really weren’t bad. The car starts better and is more playful. So if someone is looking at purchasing, I can confidently recommend Finwhale.

I am not a fan of the A17DVRM, now there are no burrs on the side, the spark plugs are made neatly, in appearance they cannot be distinguished from Bosch. But the fact that they don’t run much is a fact, the central electrode of the “semnashki” feels like it’s made of real copper, it burns out quickly, on machines with HBO this is especially noticeable, the same NLCs live several times longer.

I took NGK spark plugs - the ceramic insulator burst on one spark plug, the mileage was comical.

I tried changing BOSCH, BOSCH itriut, FINVAL spark plugs, but on NGK the effect is less pronounced.

Recommendations for replacing spark plugs on a VAZ 2114

When is it time to replace the spark plug?

The operating range of spark plugs is usually from fourteen to twenty thousand kilometers. However, the deadlines that manufacturers set for factories are much longer - thirty thousand kilometers. Perhaps such a significant difference in numbers was due to the large number of counterfeit products in the modern auto parts market. And, nevertheless, if you trust the opinion of experienced car owners, then it is better to carry out the replacement procedure sooner rather than later.

What problems can cause used condition:

• The car will become more expensive to operate.
• The engine will no longer be stable.
• Starting a cold engine will become difficult and take a long time.
• Gasoline consumption will increase significantly.
• There will be misfires during ignition.

Useful tips: Thrifty drivers often put off purchasing and replacing spark plugs. This is mainly done for economic reasons. But, as you already know, due to their severe wear, gas consumption increases significantly, and visits to service stations become more and more frequent. Don't get carried away by the illusion of saving, change regularly.

If your car managed to travel an impressive mileage on a set of spark plugs, and the car’s traction began to weaken, then your VAZ 2114 already requires replacement of the spark plugs.

Is there a difference in brands and manufacturers?

There is a difference, and it is significant. Before purchasing new spark plugs, you should read your vehicle's owner's manual and check which rating is appropriate for your vehicle. For VAZ 2114, replacement spark plugs can come from domestic and foreign manufacturers. Contact ignition carburetors fit the A17DV spark plug with a 0.5mm gap. For carburetors with a contactless system, the same will do, but with a gap of 0.7 mm. For those who have injectors, the 1.3mm A17DV-10 is more suitable.

What you might need

Before you start, you should stock up on:

• Special spark plug wrench;

• A small can of compressed air (or a tire compressor);

Compressed air cylinder

• Brush for cleaning burns and dirt;

• I have already bought a set of new candles.

Spark plug set for VAZ 2114

Replacement procedure

1. Let’s turn off the engine and be sure to wait until it cools down;
2. Raise the hood and lock it in the open position;
3. If your engine capacity is 1.6 liters, then you will have to unscrew the fasteners and remove the plastic cover (owners with an engine capacity of less than 1.6 liters do not need to undergo this procedure because they do not have this plastic cover on their car );
4. We take out the high-voltage cables from the rubber plugs;
5. Use a brush to remove any dirt and carbon deposits that have formed;
6. We unscrew the spark plug by throwing the spark plug wrench onto it;
7. We repeat the same steps with the remaining old candles;
8. The new spark plug should be inspected again, check the gap between its electrodes;
9. First, we tighten the new part by hand, and not with a tool, this will prevent the wire from breaking if the installation suddenly turns out to be incorrect;
10. We continue the tightening procedure, but using a tool;
11. We connect the previously removed high-voltage cables (the explosive contacts must fit tightly to the spark plug).

Attention! A common mistake made by novice car enthusiasts. Each spark plug has its own high-voltage wire. They should under no circumstances be confused. Connect the wire to the cylinder in series, following the marking rules.

Do not tighten the parts too sharply; their threads may be severely damaged by sudden movements of force.

After replacement

Unpleasant surprises can await car owners even after replacing old ignition parts with new ones. This can happen if the store sold you a low-quality spark plug. In this case, the engine clicks and runs intermittently. Of course, the faulty part must be replaced again. And to determine which one is faulty, you will need to disable the explosives one by one. When the wire with a faulty spark plug is disconnected, there is no change in engine performance.

How to extend the life of a candle

The idea of ​​extending the life of our side sounds very tempting. The question is how to do it correctly? Some drivers are confident that the spark plug will last longer while driving pleasantly. And they are wrong! Spark plugs do clean themselves, but only when driving fast. At high engine speeds, it is freed from the deposits that have formed.

Besides high speeds, you can extend its life by checking the distance regularly. The latter must be within the limits established by the factory. Final recommendations:

1. Select new replacement plugs carefully. They should fit your vehicle best.
2. Allow the engine to warm up well before driving in winter.
3. Under no circumstances should candles be flooded.
4. Always carry a spare set of new candles with you.

How to choose the right spark plugs for a VAZ

When choosing the best spark plugs for a VAZ engine, you should be guided by the parameters of the car and engine:

1. Heat number. If a spark plug is approved for use on a specific car, then it will be suitable in terms of its thermal characteristics. Small deviations play a seasonal role and depend on the owner’s driving style.
2. Geometric dimensions - diameter and thread pitch, length of the threaded part of the body. Protrusion or recession of the electrode area into the material of the block head is not allowed.
3. The nominal gap between the electrodes can be adjusted. The spark plug will operate uninterruptedly at the factory-set value.
4. The wrench size is of secondary importance and affects the applicability of the existing tool. It is always safer to choose the size that matches the factory size.
5. The sticking out of the electrodes has an indirect effect; the heat rating depends on it.

How to choose spark plugs

There are several general recommendations that you need to heed, namely:

1. An important aspect is the heat value; it indicates the rate at which heat is removed from the electrode insulator cone. When heat transfer is balanced, soot does not form on the candles.
2. Pay attention to the spark gap between the central and side insulators, which is determined by engine manufacturers and must comply with the parameters. With an increased gap, the spark is unstable, breakdown of the insulator is possible; therefore, misfires occur at high speeds. Another characteristic sign is popping noises in the muffler. If the gap is narrower, then the spark is more powerful and short-lived, the mixture does not have time to ignite and the spark plug floods. At high speeds, the ignition coil may short out. All these phenomena lead to dangerous disturbances in engine operation.
3. For VAZ cars, the main property of spark plugs is considered to be the protrusion of the main part of the electrodes. Therefore, products for 8-valve engines with injection and carburetor engines are produced with electrodes slightly protruding forward. For multi-valve power units, spark plugs with electrodes recessed inside are suitable.
4. You can pay attention to the number of electrodes, but as practice has shown, this parameter does not affect the quality of the candles.
5. It is advisable to purchase candles from trusted manufacturers and suppliers to avoid counterfeits.

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.

BRISK Classic L15Y

A characteristic feature of the Classic L15Y model is the ability to operate at reduced secondary voltage energy, which is suitable for older VAZ cars. A slightly lower heat rating and a small gap allow you to confidently start the engine at sub-zero temperatures; the spark plug warms up quickly and is not prone to sparking and carbon deposits.

However, because of this, the products may fail under loads and high temperatures, but for low-powered classic VAZ engines this will not be a discouraging factor. The service life is average in the class of budget candles based on copper and nickel.

The cost in the store is about 80 rubles per piece.
