Denso spark plugs for Priora 16 valves

A malfunction of the spark plugs immediately affects the operation of the engine; it begins to stall, jerk, does not pull, or starts poorly. To solve the problem, simply replace them with new ones, but which spark plugs are better to choose?

All modern 8 and 16 valve power units have the same manufacturer's recommendation. In other words, advice on choosing spark plugs will be similar for all modern Lada cars.

In the user manual for Lada Priora, Kalina, Granta, Vesta Largus, Niva and XRAY cars, the engine technical specifications contain the following data:

Engine

VAZ 11183, VAZ 11186/11189

VAZ 21126, VAZ 21127

Granta, Kalina, Largus, Vesta

Granta, Kalina, Priora

The gap between the spark plug electrodes should be within 1.1.15 mm. Let us remind you that Lada Vesta and Lada XRAY can be equipped with a Nissan-Renault HR16/H4M engine. The spark plug gap in this case should be 0.85...0.95 mm. For K4M/K7M engines (more about spark plugs), the gap between the spark plug electrodes is 0.95+-0.05.

According to the requirements, the manufacturer must guarantee uninterrupted operation of the spark plugs for 18 months, provided that the vehicle mileage does not exceed 20,000 km. However, with good technical condition of the engine and proper operation, the service life of the spark plugs can be significantly longer. Thus, spark plugs are often replaced every 3 years or after 40 thousand km.

Marketers suggest improving engine performance by installing, for example, iridium, platinum or multi-electrode spark plugs on the Priora, the price of which is higher than usual. AvtoVAZ recommends using conventional, single-electrode spark plugs for its engines. In a review by ZaRulem magazine, a survey was conducted that shows that the majority of drivers follow the factory’s recommendations and choose simple, inexpensive spark plugs.

As part of the same review, nine different spark plugs were tested. As a result, they all passed the tests, and the winner was determined by summing up the points:

So what spark plugs should I put on Priora/Granta/Kalina/Vesta? Based on the recommendations of AvtoVAZ, the test results of a popular car magazine and a survey of the social network VKontakte, we can conclude that the best choice would be spark plugs from manufacturers: NGK, Bosch, Denso, Brisk and EZ Standard.

What kind of spark plugs do you use? What is the main factor when choosing them? Let us remind you that a high-quality battery also affects engine starting.

The durability of the engine and its service life largely depend on the condition of all its components and parts, as well as on the quality of consumables that are used to service the power unit. One of the most important elements on which the trouble-free operation of the engine directly depends are the parts that ignite the fuel, spark plugs. According to the Priora operating instructions, after every 30 thousand km, it is necessary to replace the spark plugs. However, this interval can vary significantly in one direction or another, depending on many factors that should be considered in detail. In addition, you need to have a good understanding of what spark plugs can be installed on a VAZ 2170.

When do you need to change spark plugs?

The replacement interval of 30 thousand km is very arbitrary. The AvtoVAZ company equips Priora engines with domestically produced single-electrode spark plugs marked A17DVRM for a 16-valve unit and AU17DVRM for an 8-valve unit. Practice shows that even on a new car, these spark plugs often fail long before the end of the service interval, causing unstable engine operation and increased fuel consumption. For this reason, many car enthusiasts prefer imported products.

What spark plugs does AvtoVAZ recommend for the Lada Priora?

The manufacturer recommends installing spark plugs Brisk “SUPER” DR15YC-1, Brisk DR17YC-1, Bosch FR7DCU, as well as AU17DVRM or AU15DVRM. These spark plugs are the most popular and are recommended by the factory. Their resource is designed for 30 thousand km, after which it is better to replace the spark plugs.

The advantage of iridium or platinum spark plugs is their service life, which is longer than conventional spark plugs. If conventional spark plugs require replacement after 30 thousand km, iridium spark plugs can last up to 60-70 thousand km.

After purchasing spark plugs, we recommend checking them. You can do this yourself, if you or someone you know has the device, or in a car service center at a special stand.

Description of types and markings

When the need for replacement arises, you should decide which candles are best to install. The most popular brands are Brisk, NGK and Bosh. However, they have different markings adopted in Europe, so you need to know which imported candles correspond to the domestic markings. The interpretation of this marking, according to OST 37.003 081 - 98, is as follows:

The first letter A means the type, diameter and thread pitch - M 14 x 1.25.
If the letter U follows, it indicates the size of the hexagon for tightening the spark plug, 16 mm. In the absence of the second letter, the product has a size of 20.8 mm.
The number 17 shows the heat number. When the engine is running, the spark plug heats up to a certain optimal temperature, at which it self-cleanses. In the event of unfavorable operating conditions, overheating of the electrodes occurs, and the fuel in the cylinder can ignite spontaneously, without waiting for a spark to occur. This effect is called glow ignition, and the glow number of a candle is a parameter indicating the temperature regime of its proper operation. The higher this parameter, the less the product heats up (cold candle) and can work in much more difficult conditions than a candle with a low heat rating (hot). In engines with high power and high speeds, colder spark plugs are used, and for power units with lower loads, hot products are used.

Marking of imported spark plugs on Lada Priora

The letter D indicates the length of the thread (skirt) - 19 mm.
The letter B means that part of the insulator protrudes above the plane of the product body.
The letter P indicates that a resistor is built into the spark plug body to suppress interference from sparking.
The last letter M indicates that the central electrode is bimetallic with a copper core.

Recommendations for replacement

This operation is extremely simple; any car enthusiast can change the spark plugs on a Priora. You must have a 10mm wrench and a spark plug wrench with a universal joint and a rubber bushing, which is located inside the hexagon and allows you to pull spark plugs out of deep wells. Instructions for performing the work:

Open the hood and remove the plastic decorative panel from the engine; on the Priora it is attached with rubber bushings and removed by hand.
Remove the terminals from the ignition coil, then use a 10 mm wrench to unscrew the fastening bolt and remove the coil.
Insert the spark plug key into the well and push it onto the spark plug until it stops, carefully loosen it and unscrew it, and pull it out of the well along with the key. It happens that the candle cannot be weakened. In this case, you cannot force the key; you need to try to do it on a hot engine. If this does not help, you can treat the wells with WD-40 aerosol lubricant, then put a short piece of metal tube, up to 40 cm in size, onto the spark plug wrench knob. Very carefully apply force to the lever and move the spark plug along the thread. If the tube or key begins to bend from force, and the spark plug does not give in, you need to complete the process and seek help from a car service center.
After checking the gap between the electrodes, insert a new spark plug into the hexagon of the key, immerse it in the well and screw the spark plug into place. Tighten by applying manual force to the key knob, without any additional levers, otherwise it will become problematic to loosen the spark plug next time.
Reinstall the ignition coils in reverse order, insert the terminals and put the decorative panel on the engine. Start it, make sure it is working properly and close the hood.

The correct choice of a set of spark plugs for the Priora and their timely replacement in the event of a malfunction will extend the life of the engine and help prevent serious consequences from incomplete combustion of the fuel mixture.

Classification

You need to approach your choice as responsibly as possible. It is worth deciding which type of spark plug is best suited for the car. So, these elements have their own classification according to:

Number of electrodes: two- and multi-electrode. The first type consists of several elements. These are the side and central electrodes. These are installed standard on Priora. As for the second type, they have one central and three side electrodes. 14fr7du. What spark plugs are currently best for VAZ 16 cl.? As reviews note, these candles have a longer service life and are more reliable.
Type of material. Often spark plugs are equipped with copper electrodes. What are the best spark plugs for Priora? Judging by the reviews, they have a short resource - up to 30 thousand kilometers. But recently more “tenacious” iridium analogues have appeared on the market. Their resource is about 60 thousand. By the way, such candles have a slightly smaller diameter of the central electrode. If on copper it is 2.5 millimeters, then on iridium it is 0.7 millimeters.
Thread diameter. When purchasing, check with the seller for which engine you need spark plugs. Thus, 16-valve valves are equipped with elements with a smaller head size and thread diameter. Spark plugs from an 8-valve engine simply won’t work in a 16v Priora.
Heat number. This parameter means the pressure at which it is easier to heat the candle. Candles for Priora 16 cl: which ones are better to install. There is a cold and a hot type. The glow number of these candles is 20 and higher for the first and 11-14 for the second. Which spark plugs are better for Priora 16 cl.? There is no clear answer to this question. According to Auto-VAZ recommendations, spark plugs for 16 valve Priora are which spark plugs are best for 16. But there are also universal options. In this case, the glow number is from 11 to 20. These are the spark plugs that many motorists use. They behave well both in summer and in cold weather.

Read the auto review! There are spark plug tests!

In Autoreview, a test of spark plugs for 8-valve engines, I didn’t find a source called Autoreview, but the question about 16-valve engines is first, and about replacing some spark plugs with others, secondly.

I put Denco Q20PR-U11, at one time I saw them in the VAZ recommendations, and not the ones you listed. I haven’t tried others, there was no need

Read the auto review! There are spark plug tests!

The only difference between the candles is the turnkey size!

Thanks for the review, my hand involuntarily reaches for “b”

we will fix it.

What does the manufacturer recommend?

The Volzhsky Automobile Plant regularly uses spark plugs marked AU17DVRM. . Judging by the reviews, the service life of these spark plugs is 25 thousand kilometers. This is quite good, considering the low cost - 400 rubles per set. But products with this marking perform poorly in cold weather. What spark plugs should I put on the Priora 16 valves for winter use? Here it is better to use “Priority A 15 DVRM”. These candles have a lower heat rating. They ignite more easily at subzero temperatures.

Analogs

Candles from German. They are little popular, but have a high resource. The marking for Priora is 14FR7DU.
Japanese candles NGK. Zheka147 › Blog › Which spark plugs are best to choose for which spark plugs to put on Priora a for 8. Perhaps the most popular analogue of factory products. For the 16-valve Priora , NGK marked BCPR6ES is ideal.
"Denso". This is also a Japanese manufacturer. The cost is on par with NGK, and the quality is not inferior either. For Priora you should buy Denso Q20PR-U11.
"Brisk" (Czech Republic). Another popular spark plug manufacturer. The manufacturer offers products with different heat ratings and number of electrodes. Spark plugs DR15YC-1 are suitable for Priora The same ones are used on Kalina engines of the first and second generation, with a 16-valve timing mechanism. But judging by the reviews, the products are of low quality - the electrodes are greatly offset from the center, which is unacceptable for such products.

What does carbon deposits on spark plugs indicate?

The first picture shows a working candle with a little soot. A small deposit on the insulator and electrodes may be caused by bad or poorly functioning PVN (armored wires), a rich mixture or an ignition delay

The second picture shows a candle with a brownish-yellow soot; sometimes there are candles with a glossy insulator without soot, as if polished. The reason for this may be the use of fuel with a high octane number that is not suitable for the car.

If overheated, the spark plug will have a white insulator with small black deposits and premature electrode erosion. The reason for this may be ignition advance, or a spark plug that is not fully wrapped.

If the spark plug electrode is melted or partially deformed, this indicates premature ignition. This leads to loss of engine power, as well as rapid engine wear.
