Good spark plugs for Lada Kalina

About candles

The spark plug in the engine is a very important element, without which the internal combustion engine simply will not work. At the moment the spark is applied, the fuel mixture in the combustion chamber is in a compressed position, when a spark appears, the mixture ignites and an explosion occurs, thereby pushing the piston down. The spark plug serves as a link between the ignition coil and the combustion chamber.

The difference between candles

Two types of engines with 8 and 16 valves were installed on the Lada Kalina. The type of spark plugs depends on the number of valves. The difference between the spark plugs in a 16-valve engine is the smaller diameter of the hexagon, since these spark plugs are placed in the spark plug well, where there is a rather narrow distance from the walls, which does not allow the use of spark plugs with a 21mm hexagon.

Spark plugs from a 16-valve engine can be installed on an 8-valve engine, but vice versa will not work, spark plugs from an 8-valve engine will not fit into the spark plug well.

Candle device

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.

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

Also, depending on the inconsistencies present, other malfunctions may “pop up” that reduce the comfort of using the car.

What to look for when choosing.

Specialists from the AvtoVAZ plant recommend selecting spark plugs according to a number of parameters.

Heat number. The parameter characterizes the rate of heat removal from the working part of the candle. At the same time, the electrode transfers excess heat to the spark plug skirt in a timely manner, which ensures stable operation of the part. If energy is removed too quickly, scale forms on the working part of the part, which prevents normal spark breakdown. If the withdrawal is too slow, the thin electrode overheats. The process provokes the formation of glow ignition. This prevents the engine from operating normally due to detonation of the mixture or its early ignition. Under normal thermal conditions, a spark adequately breaks through the spark plugs and does not form excessive carbon deposits.
Spark gap. Some users know that for the engine to operate correctly, the spark gap on the spark plugs must be maintained. The working gap on VAZ spark plugs is strictly set by the manufacturer of the power plant and is necessary due to the fact that the formed electric arc has a certain strength. As the distance increases, the spark loses stability, which can lead to misfires. In the opposite case, easier starting of the engine is ensured, but when the gas is released, the electric arc current may not be enough. This is justified by the fact that each ignition coil has a certain transformation ratio, usually equal to 2000 units. This means that during the start-up of the internal combustion engine, the elements produce up to 14 kW, and during normal operation it is already 24. Consequently, failure to comply with this parameter can lead to serious disruptions in the operation of the motor.
Departure of the working part of the electrodes. The parameter is critical for adequate operation of the power plant. The spark plugs on the VAZ 8-valve injector, as well as for carburetor models, have electrodes strongly pushed forward. This is due to the fact that the structural parts are located in the corner of the combustion chamber, where there is no adequate ventilation. The overhang of the working part allows for better ignition of the mixture and stabilizes engine operation. If the spark plugs are mounted in a multi-valve engine, where the inserts are located in the center of the valve head, it is recommended to install spark plugs with a deep-set core - this will prevent damage to the electrodes by the piston bottom and an abundance of carbon deposits on the structural elements.
Number of electrodes. Initially, manufacturers position this parameter as a definite plus. When one electrode “burns out,” the spark plug switches to another, which significantly increases its service life. However, not everything is as simple as it seems at first glance. If the mixture is sprayed unevenly in the cylinder (poor ventilation of the combustion chamber), and at this moment the spark jumps to the shadowed part (the place where the exhaust remains), misfire may occur, which will lead to unstable operation of the power plant. Additionally, this fact increases the wear of the catalyst and engine oil, which is critical for VAZ cars.
Manufacturer. The manufacturer of the product is also an important parameter. Users recommend buying from trusted brands that have been on the market for a long time. The cost of such candles will be significant, but with proper selection and operation they will work for a long time and without significant complaints.

By adhering to the specified parameters, a car enthusiast can buy a fairly high-quality product, while saving on the frequency of car servicing and repairs.

When is it necessary to replace spark plugs?

The replacement of spark plugs is carried out no later than 40,000 km, since by this mileage the wear of the insulators on the spark plugs is already quite decent, and the temperature may increase the gap between the contacts, which will lead to incorrect operation of the spark plug.

You should also first replace the spark plugs if misfires are detected in the cylinders or unstable engine operation, interruptions in operation and loss of power.

How to replace spark plugs

Before installing a new product and removing failed spare parts, you must disconnect the negative pole of the battery, which, unlike the positive one, is black and has a “-” symbol. The cost of replacing the device is very low, starting from 150 rubles each. The cost will increase or decrease depending on the volume and number of cylinders.

On average, gasoline vehicles are serviced every 60,000 km. However, depending on how intensively the car is used, this interval may be shorter and the glow system will fail between 35,000 and 40,000 km.

Remember that if only one spark plug is faulty, it is advisable to replace them all at once. Below we provide step-by-step instructions necessary for installing the equipment:

a wrench of a certain width so that you can unscrew and secure the new device;
ratchet or hexagonal head to facilitate removal of the product;
a compressor with compressed air to thoroughly clean all openings and connections;
goggles to protect your eyes from debris that may bounce off during blowing;
You need to put gloves on your hands, they will come in handy when working with cables.

1. First of all, keep in mind that the engine must be cold, you need to start working after 2 hours from the moment of using the equipment. The spark plugs are usually visible or under a plastic protector. They have a characteristic shape that will be very easy to find.

2. Disconnect the high-voltage cable from the required plug, carefully pulling it towards the top so as not to damage it. Do this carefully, remembering the location of all the wires so that you can then secure everything in its place.

3. Remove the fork and spool using a hex wrench, appropriate ratchet, or wrench. To remove the device, you need to turn the tool counterclockwise.

4. Then blow out the mounting hole, completely clearing it of dirt. It is important to wear safety glasses when doing this.

5. Secure the new product. Lubricate it and start screwing it in carefully by hand, applying a little force, then use a wrench to tighten the device, being careful not to overdo it too much.

6. Insert the ignition coil, tightening it with the screws and ratchet you used earlier. Be careful not to apply too much pressure as this may damage the threads and the reel itself.

7. Connect the cable and repeat the same process for each design.

If you did everything correctly, used the appropriate key size, unscrewing the heads, the car will start and work more efficiently.

Choosing spark plugs for the engine 21116 and 21126

According to technical regulations, spark plugs in engines 21116 and 21126 should be changed during maintenance-2, that is, after 30 thousand km. In fact, this period can be extended by one and a half times if we are talking about gentle operation. But you shouldn’t do this if the car is under warranty (then the replacement is carried out according to the regulations). Here we will list which spark plugs are suitable for each of these engines. We will assume that the owner of Kalina-2 uses the catalogs of the following companies: BERU, CHAMPION, NGK, DENSO, BRISK, BOSCH.

AvtoVAZ’s recommendations for choosing spark plugs look like this:

JSC ZAZS (Russia) – AU17DVRM, A17DVRM;
BERU (Germany) – 14FR-7DU, 14R-7DU;
CHAMPION (England) – RC9YC, RN9YC;
NGK (Japan) – BCPR6ES, BPR6ES;
DENSO (Japan) – Q20PR-U11, W20EPR;
BRISK (Czech Republic) – DR15YC, LR15YC;
BOSCH (Germany) – FR7DCU, WR7DC.

On the left is the brand of the product suitable for a 16-valve engine, on the right is for an 8-valve engine. You may notice that spark plugs with thin electrodes, iridium, etc. were not listed here. A thin electrode is then used to ensure reliable ignition at high speeds (7,000, 8,000 rpm or more), but for VAZ engines above 6,000 rpm the cutoff is triggered. Iridium spark plugs have a thin central electrode in their design, but as we have already found out, switching to using such parts is a waste of money, and nothing more. The durability of iridium spark plugs approximately corresponds to the “lifespan” of a spark plug with a standard copper electrode. We leave the choice to the owner.

What candles to put in Kalina

The manufacturer for Kalina recommends domestic spark plugs of type A17DVRM (for 8-valve engines) and AU15DVRM, AU17DVRM (for 16-valve engines), as well as their foreign analogues. For example, for 8-valve cars, spark plugs BRISK LR15YC (Czech Republic), BOSCH WR7DC (Germany), NGK BPR6ES (Japan) are suitable, for 16-valve cars, respectively, BRISK DR15YC, BOSCH FR7DCU and NGK BCPR6ES.

All of the above spark plugs are single-electrode – this is the type again recommended by the manufacturer. It is not prohibited to install multi-electrode analogues (it is believed that they give a better arc), just keep in mind that they will cost a little more, and you may not notice the effect. As for iridium and platinum spark plugs, their main advantage is their long service life.

Ceramic deposits have appeared - change the spark plugs immediately!

In terms of their operational parameters, including durability, all components of the listed items are almost the same from each other. This is confirmed by reviews from car owners expressed on various forums, etc. Perhaps there are more expensive components, the use of which will allow a simple replacement to increase power, engine torque or some other characteristics. But having installed such spark plugs in the 21126 engine, you will most likely have to forget about the warranty on the AY-K3 gearbox. It’s always like this with technology: we need to imagine what exactly we are doing and what we want to achieve as a result.

Selection of spark plugs for modern VAZ engines

Indications for replacing spark plugs:

If there is black soot (“suede”) on the insulator cone and electrodes, then cleaning or replacement can be done. Cleaning is carried out, among other things, by heating. When replacing, it is better to use spark plugs with a slightly lower heat value than before;
If the surface of the insulator looks like yellowish glossy ceramic, then the spark plug needs to be replaced. In this case, a glassy glaze is formed. It is electrically conductive.

In the first of the cases considered, carbon deposits are formed because not all elements of the candle are heated sufficiently, and self-cleaning does not occur. This can happen when the car is used for short trips with low speeds and frequent starts and stops. The same effect is typical for operating the motor at low temperatures. Logically, in such situations, the recommended replacement would be a spark plug with a lower heat rating than what was intended by the manufacturer. You can try installing A14DVRM spark plugs instead of A17DVRM in an 8-valve engine, and so on. Only now, such a replacement must be discussed with the dealer.

Comparison of A17DVRM analogues produced under different brands

One of the online publications conducted a comparative test of spark plugs intended for the VAZ-21116 engine. We tested analogues of the A17DVRM spark plug, supplied by the following companies:

APS, Bosch, Brisk – Russian production;
Bosch Platinum, Beru, Finwhale – Germany;
NGK, Denso – Japan;
Eyquem - France;
Champion – “made in the European Union”.

Note that testing was carried out on an 8-valve VAZ-2111 engine (injectors, lambda probe, without catalyst, “January-5.1”). All measurements were carried out on a bench.

Selection of spark plugs for 8-valve engine 21116

The results of the tests performed are presented in the photo in the form of graphs. As you can see, it still makes sense to buy imports: using spark plugs from Bosch, as well as products from the Finwhale, Brisk and Champion brands will provide a noticeable increase in power. If you want to save on fuel, then ask for NGK products in stores. Additional comments are unnecessary here.

Forced engines are characterized by an increased compression value, and VAZ engines are no exception. By installing Brisk spark plugs, you don't have to worry about sparking at high pressure. But note that NGK candles have similar characteristics. It turns out that NGK products should be considered the optimal choice, however, recently counterfeits of this brand have appeared. And the “remake”, it seems, is now coming from France, as described in the film.

Which brand is better?

As a rule, LADA Kalina owners prefer spark plugs in the mid-price segment. These traditionally include domestic products from EZ

(placed on the assembly line) and Czech
BRISK
.
NGK
spark plugs
Denso
equivalent .
The reliability of original Bosch
extends their service life - they last much longer than the period for routine replacement.
BERU
are also trustworthy - despite the attractive price, the igniters behave excellently in VAZ engines.

High-quality brands may have one indirect drawback - the presence of counterfeit products on the market. There are only two ways to combat this - carefully study the product and packaging, and be selective in choosing a supplier. It is better to trust a well-known retail chain with a reputation or official representatives of the brand. In this case, the likelihood of acquiring a counterfeit product is minimized.

Tips for choosing spark plugs for Lada Kalina

The choice of igniters for the LADA Kalina engine is not particularly difficult and largely depends on the size of the budget allocated for replacement. There are a few key features to consider when making your purchase:

Heat number.

Based on this parameter, it is recommended to choose medium spark plugs (15-19) for the Lada Kalina. If you take a cold one (14 and below), then not only an improvement in spark formation will be observed, but also overheating of the igniter. If the quality is low, the candle will quickly fail. A heat rating of 20 or higher in 1.6 engines leads to misfires and carbon deposits.

Dimensions.

These values must be strictly observed:

Material of the central electrode.

Affects the quality of spark formation and the durability of the spark plug. Copper and nickel cores are the most common. Yttrium alloy demonstrates increased throughput at a low price. The most expensive spark plugs come with electrodes coated with platinum or iridium - they are durable and reliable in any conditions. Their service life depends on the model and can range from 60 to 120 thousand km.

Symptoms of replacement

The process of replacing spark plugs is quite simple and can be done independently.

According to the manufacturer's regulations, spark plugs must be replaced every 30,000 km . However, in the harsh Russian realities, not every detail is able to work out the time allotted to it.

The following signs indicate the need to replace spark plugs:

The starter spins longer than it should when starting the engine.
Gasoline consumption has increased.
Extraneous sounds are heard from the engine during the warm-up process. Why does the engine take a long time to warm up?
Reduced motor power . This is especially noticeable when trying to drive up a mountain.
The spark plugs are "wet from gasoline". That is, they are flooded. To check, you need to unscrew the spark plugs and inspect them.

Too uneven carbon deposits on the electrodes of the spark plugs indicate problems in the operation of one or another cylinder.

Soot on spark plugs does not always indicate that they need to be changed. If the mileage is still low, then the consumables can be cleaned. For example, a gray-yellow or brown coating indicates that the electrodes are not very worn.

Top 5. BERU Z21 (14R-7DUX)

The low heat rating and high conductive characteristics of the materials used in the BERU Z21 spark plug contribute to the reliable operation of the internal combustion engine. Lada Kalina shows excellent dynamics even with a very lean fuel mixture.

Average price: 144 rub.
Country: Germany
Electrode: yttrium
Gap, mm: 1.1
Heat number: 7
Resource, km: 30000

An excellent choice for LADA Kalina owners instead of factory spark plugs. The service life of BERU igniters more than covers the replacement interval recommended by the car manufacturer. The use of the latest developments in the field of conductive materials gives spark plugs the ability to confidently work with very lean mixtures. After installation in a Lada Kalina with a 1.6 liter internal combustion engine with 8 valves, smooth operation at idle and no misfires at high speeds are observed. This has a positive effect on acceleration dynamics. Among the disadvantages - 14R-7DUX is not always on sale; for a planned replacement it is better to order spark plugs in advance.

How often should you change spark plugs on a Lada Kalina?

Replacing spark plugs on a Lada Kalina is a very simple and not too expensive procedure. However, it is not always necessary to replace consumables; it is quite possible that the old spark plugs will serve you a little longer.

Which spark plugs are best for an 8-valve Kalina

AvtoVAZ recommends several options for spark plugs.

A17DVRM - original number. A27DFID is a more modern analogue, and according to reviews it is better. The cold start problem goes away.

The most budget option is spark plugs A27ДМРВ produced by JSC Robert Bosch Saratov.

German spark plugs from BERU – 14R-7DU ;
Japanese NGK–BPR6ES (very frequent replacement, good spark plugs according to reviews);

Candles NGK–BPR6ES in branded packaging in bright colors.

Iridium spark plugs

NGK – BPR6EIX11 ;
DENSO – IW20TT .

Which spark plugs are best for Priora/Kalina/Granta?

Recommended spark plugs for Priora/Kalina/Granta . The manufacturer recommends using domestic spark plugs A17DVRM and A15DVRM or their imported analogues. Depending on the engine model, different spark plugs are used. For example, spark plugs on a Priora have 16 valves: AU17DVRM, and for 8 valves: A17DVRM. Spark plug compatibility table for all VAZ cars:

Catalog numbers of VAZ spark plugs.

Lada Priora: 21120-3707010-00, 21120-3707010-01.
Lada Kalina: 21110-3707010-00, 21110-3707010-01.
Lada Granta: 21110-3707010-00, 21110-3707010-03.
Lada Kalina 2: 21110-3707010-00, 21110-3707010-03.

The price of spark plugs depends on the manufacturer and region. Approximate cost 200-500 rub. per set.

Types of spark plugs . Spark plugs can vary in the number of electrodes: single-electrode (standard), multi-electrode. And also by type: Regular (standard), iridium, platinum. The manufacturer recommends using conventional single-electrode spark plugs for VAZ.

The service life of spark plugs depends on operating conditions. In accordance with the maintenance regulations for Lada Priora, Kalina and Granta cars, spark plugs should be changed every 30,000 km. However, in some cases (for example, when starting the engine in severe frost), new spark plugs can be damaged by filling them with gasoline. Advice: do not throw away old candles, but use them in such cases.

By the way, the owners of the tenth family of VAZs in the survey “which spark plugs to install” identified the best spark plugs: NGK, Denso and Brisk. And the review/test of spark plugs by ZaRulem magazine identified other leaders:
