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

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.

How to choose the right spark plug

It is important to purchase high-quality spare parts for a car; in order to buy a good product, you need to pay attention to the following selection criteria:

1. It is necessary to order a product compatible with the machine's engine. Most of the best brands clearly indicate the vehicle models their product will be compatible with. Therefore, you need to carefully review the manufacturer's compliance list.

2. Apart from compatibility, you need to choose the design type as there are various options available. The most common:

• Copper-Nickel: The name may confuse you because these products are primarily made of nickel, with only the inner core being made of copper. It conducts current well, which is why most electrodes are made from it. The product is inexpensive, its disadvantage is that it has a short service life, even if used in a high-energy ignition system without a distributor. Many vehicles will benefit from this option; it is suitable for natural gas engines.
• The next type has a platinum center contact. It is expensive due to the rarity of this element, which is harder than nickel, so you can be sure that the product will not corrode. The platinum will prevent the tip gap from widening and wearing out, which directly affects the efficiency of the engine. There are models with one or more electrodes. This helps generate the spark in the best possible way. In terms of service life, it is twice that of standard nickel/copper construction.
• Iridium Product: If you want flawless, smooth motor performance, there is nothing better than an Iridium product. It has a longer service life than traditional models. The thin wire central contacts are designed to conduct current most efficiently. These are expensive products, but the price is offset by incredible performance.
• Silver candles are an option with the best thermal conductivity. The problem with this product is its durability. The precious metal cannot match the durability of platinum or iridium models.

All designs fit any vehicle in one way or another, but the platinum-based option is more universal. It is relatively affordable than iridium and much better in performance and durability than copper-nickel devices.

3. It is important to decide: “What kind of ignition is needed, cold or hot?” To give a very simple but precise definition, we can say that candles that glow during operation are hot. And those that do not reach high temperatures are cold.

The metal shell of the structure operates at the same heat as the head. The elements are screwed to each other, forming a chamber in which heat is distributed evenly. Hot models have a long insulator tip with a large surface area, causing all parts to become hot. At the same time, cold ones have a small cap that helps quickly remove excess degrees from the combustion zone.

Russian-made models usually have a numerical heat rating. Their assessment is not always consistent because some brands give higher values ​​while others underestimate.

It becomes extremely difficult for buyers to choose the right product with so many options. It is best to order the design in accordance with the car's engine and year of manufacture.

4. If you do not want to suffer for a long time during replacement, it is better to choose a design that is easy to install. By applying the above selection criteria, a productive model can be easily determined.

Below is a table of compatibility of spark plugs for a Lada car:

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.

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:

1. The starter spins longer than it should when starting the engine.
2. Gasoline consumption has increased.
3. Extraneous sounds are heard from the engine during the warm-up process. Why does the engine take a long time to warm up?
4. Reduced motor power . This is especially noticeable when trying to drive up a mountain.
5. 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.

Kalina standard spark plugs

The manufacturer installs spark plugs of type AU17DVRM from the assembly line. These candles have proven themselves well and are quite reliable. There are also a large number of imported analogues that are in no way inferior to domestically produced candles.

Below is a table with candles that are perfect for Lada Kalina.

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.
