Ranking of the best spark plugs for cars in 2021

When choosing which spark plugs are best in 2021, dealers are advised to look at the car's manual to see the recommended type of consumables. The main selection criterion is the glow number. The higher it is, the faster the cooling rate of the candle. Accordingly, if 11-14 is indicated on the package, then it cools slowly and is suitable for machines operated only in urban conditions.

If you are planning long-distance trips, then look for the glow number to be greater than 17. It is also necessary to take into account the material from which the spare part is made and the number of side electrodes. The size of the gap between them is of great importance. The efficiency of combustion of the mixture in the cylinder, as well as the quality of fuel combustion, depends on this.

You should not save on such consumables, because not only the quality of the engine's operation, but also its durability depends on this. With the correct selection of candles, you can improve the acceleration speed and reduce the amount of fuel consumed. Next, we will tell you which spark plugs are considered and what are their characteristics.

Top 5 best spark plugs of 2021

Spark plugs are needed to spark and ignite the fuel in the engine's combustion chamber. If they are not replaced in time, there will be nothing wrong with the car, just the time will come when the car will not start and you still have to run to the car market. With well-chosen spark plugs, the engine runs smoothly and the consumption of diesel, gas or petrol remains stable.

It is enough to find "your" model once, so that in the future you will not worry about the engine resource, its safety and, in general, whether the car starts or not.

The rating of the best spark plugs of 2021, according to drivers' reviews, includes the following models:

• Husqvarna HQT-10 is a product of a famous Swedish brand of automotive products.
• Denso 3445 XU22HDR9 - the Japanese quality of consumables from this manufacturer is, as always, on top.

This list of 2021 spark plugs is not exhaustive. There are many more manufacturers on the market offering quality products. We have collected models of consumables that best meet the price / quality criterion. You can use the information below, or select other brands of spark plugs to keep your vehicle's engine running smoothly and efficiently.

Husqvarna HQT-10

Husqvarna HQT-10 Swedish candles with a nickel electrode can be used in any gasoline two-stroke engine of garden and construction equipment. As a rule, they are purchased for chainsaws and lawn mowers.

They made it to the top of the spark plugs for the following benefits:

1. High electrode durability.
2. Excellent performance.
3. Creates a large front of flame propagation, ensuring complete combustion of the fuel.
4. Differs in resistance to soot and rust formation.
5. Provides stable sparking and efficient engine operation in almost any vehicle.

Installing such a plug will allow you to fully utilize the engine's energy resource and increase its efficiency. One of the best engine spark plugs on the Russian market is presented at a price of only 259 rubles.

Denso 3445 XU22HDR9

If you are looking for spark plugs for your car, pay attention to the Japanese Denso 3445 XU22HDR9. It is perfect for replacing a standard spark plug, providing stable sparking and being protected from corrosion.

Its main advantages are:

1. U-groove in the side electrode for improved combustion and lower emissions.
2. Reduced fuel consumption by up to 30%.
3. Copper core for reliability.
4. The presence of a heat-resistant nickel coating.

Denso spark plugs are also ranked among the best manufacturers for their durability. They are suitable for many gasoline vehicles, and their average market price in Russia is 320 rubles.

Bosch FR7SE

Bosch FR7SE with 1.1 mm electrode gap is an excellent choice. Its core is covered with an anti-corrosion chromium-nickel sheath, thanks to which the candle works in almost any weather conditions. An additional advantage is the SAE fastening with an internal threaded connection, which allows you to install the plug yourself, without the presence of special tools and service stations. Reliable fixation of the spark plug is provided by means of an elongated threaded part, and the presence of an interference suppression resistor will improve the spark, as well as the supply of fuel and ABS.

When choosing a brand of candles, keep in mind that Bosch candles are installed on cars operating in the most difficult weather conditions, and their only drawback is an increase in fuel consumption by about 20%. Therefore, it is not advisable to install them on machines operated in milder climates.

You can buy such a candle in Russia at a price of 350 rubles.

NGK 4339 DCPR8E

NGK is one of the best spark plug manufacturers. Its model 4339 DCPR8E with an interelectrode gap of 0.8 mm is equipped with a resistor that limits the spark when the engine starts. This reduces the risk of radio interference and premature electrode burnout. Excellent for vehicles that are exposed to significant loads, although it has a relatively short service life. But if you are looking for which company is better to install candles on Chevrolet, Fiat and Lancia, feel free to choose NGK 4339 DCPR8E at a price of 350 rubles.

Bosch V6SII3328

When choosing candles for a car in a city, experts recommend purchasing a Bosch V6SII3328 iridium candle with a distance between the electrodes of 0.7 mm. This model is distinguished not only by its high performance characteristics, but also by its durability, having a platinum alloy soldered on the center electrode. Excellent for climates with high humidity or low temperatures, which makes this model an ideal purchase for use in Russia. The approximate power reserve of such a candle is from 90 thousand km, and the cost in the domestic market is from 300 rubles.

Now that you know which spark plugs are the most reliable, you can choose the right model for your vehicle. And which ones have you installed in your car and how many thousand kilometers have you already traveled with them?
