We change and select spark plugs for 16 and 8 valve Priora engines

What is a candle for?

A car's spark plug is one of the main elements of the internal combustion engine. It is this that forms a spark in the combustion chamber of the engine, thereby igniting the air-fuel mixture in the cylinder block, which sets the piston group in motion. For each car there are certain spark plugs that are recommended by the manufacturer. They differ in the long thread of the spark plug, the number of contacts, resistance and hex head.

Recommended spark plugs for Lada Priora 16 valves

The manufacturer recommends using domestically produced single-electrode spark plugs on the Priora, type: AU17DVRM. These spark plugs can be replaced with imported analogues of the following brands: Bosch, Denso and NGK.

It should be noted that it will be impossible to install spark plugs from 8-valve cars on a 16-valve engine, since the hex nut on the spark plug is larger and simply will not fit into the spark plug well of a 16-valve engine. Therefore, it is recommended to purchase spark plugs designed specifically for your engine.

Table of interchangeability of spark plugs for all Lada Priora engines (depending on the number of valves).

WHAT IS THE DIFFERENCE IN CANDLES FOR 8 AND 16 VALVE PRIORS?

As mentioned above, Priors with 8 and 16 valve engines require different spark plugs. According to Auto-VAZ recommendations, spark plugs for 16 valve Priora must comply with the A17DVRM standard, and for 16v engines - AU17DVRM.

In fact, the differences between them lie solely in the design features - devices labeled A17 fit a standard hexagon, AU17 - a smaller one.

You can see the features of marking of domestically produced products in the image.

The best spark plugs for Priora

During surveys on website forums, it was revealed that most of all Prior owners trust domestic spark plugs AU17DVRM and spark plugs NGK N11. It is these products of domestic and Japanese production that are the most reliable spark plugs for AvtoVAZ engines.

NGK spark plugs for Lada Priora

The service life of these spark plugs can reach up to 30,000 km of vehicle mileage, which is quite good. But these figures can only be obtained with proper use of the car, because even new spark plugs can quickly fail. Quite often, spark plugs fail precisely because the internal combustion engine is started in cold weather. They are filled with gasoline and eventually pierce the insulator or electrode, after which the spark plug becomes inoperative.

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.
