The best spark plugs in 2022

Car candles are not the product that the owner of the car is primarily interested in, but when ignition problems arise, interest immediately arises, and a lot of questions on the topic “Which company is better” or “What should be the selection criteria”.

Studying the popularity of models and their functionality, you come to the conclusion that a wide range of spark plugs are produced by manufacturers that are not related to well-known automobile companies. This has an undeniable advantage, since the logo of a promoted brand on any auto part increases its cost by a quarter. From this it follows that it is better to buy consumables from the manufacturer, thereby avoiding a significant markup from the automaker.

How to choose the right spark plugs?

Which brand of spark plugs to choose?

There are different types of candles on the market today. They are differentiated according to various criteria, for example, use in gasoline or diesel engines. There are also differences related to the number of electrodes (two and multi-electrode) and the material (iridium, platinum) from which they are made.

The most popular models belong to brands such as:

• NGK. The brand successfully cooperates with such business sharks as Ferrari, BMW, Volvo, etc.
• Bosch. Supplies parts for Mitsubishi, Toyota, Audi, Fiat.
• Brisk. Creates consumables for BMW, Skjoda, Opel and Audi.
• champion. Has a contract for the creation of auto products for Alfa Romeo, Suzuki, Jaguar and other brands.
• Denso. A well-known Japanese corporation that creates high-quality spare parts for various cars.

Purchasing spark plugs from these companies will be a great savings and an excellent alternative for any brand of your car. The quality of the products is excellent and appreciated by many professionals.

Clearly about spark plugs:

Most popular designs

Ordinary spark plugs. They are classic single-electrode devices: a snow-white ceramic body on top and a threaded metal bottom. Such models attract attention with their budget price, simplicity and the ability to improve the performance of the motor. But, of course, you can not do without cons. These include the minimum resource.

Multi-electrode spark plugs. The peculiarity of such devices is that there are several additional ones around the central electrode, the so-called side electrodes.There can be 3 or 4 of them. The result is a kind of flower. The advantages of such devices are that you can make a choice from which electrode to receive a spark. And, accordingly, the service life increases. Also, the ignition of the flame passes through the center of sparking and there are no breaks in it, which favorably affects the increase in engine power.

Candles with platinum and iridium. A significant drawback of these devices is immediately evident, as this is a "biting" price tag. You might think that it is unreasonably overpriced, but in reality it is not so. Thin electrodes have the unpleasant property of wearing out quickly, and when they are made of metal, they resist destruction. In addition, such spare parts have a number of advantages: self-cleaning, the ability to additional insulation, an increased number of electrodes and other nuances. It's definitely worth paying extra for.

The best spark plugs.

77 00 500 168

Renauilt spark plugs marked 77 00 500 168 have proven themselves excellently. The technical characteristics of this spare part are great for the K7M engine. The plant constantly conducts strict quality control, which guarantees flawless work.

The French manufacturer Eyiem is the main supplier of these devices for a huge part of European factories.

Thanks to two side electrodes, the resource of candles increases. And the central electrode, flying into the combustion chamber, competently provides the ignition of the mixture.

Conducted numerous tests revealed that 77 00 500 168 are a quality product, with a decent resource, but without record performance. The cost is about 200 rubles.

• Quality at the highest level;
• Corresponds to the declared working conditions.

Denso K20XTR

The manufacturer is Japan, which cannot but please motorists, since such products are an unsurpassed copy of unique spare parts and only the marking can give out where the candles are actually created. The surface of the electrodes is made of nickel, which has a beneficial effect on erosion resistance. The high resource of the product and stable sparking ensures quiet operation of the engine and ensures that fuel consumption is normal. The average price of a car product varies about 250 rubles.

• Fine quality;
• Erosion resistant electrodes.

• Price.

Beru Z193

This is a kind of classic of the genre and is popular with buyers. Candles confidently serve their term from one MOT to another, do not let the owner down, but at the same time they do not amaze with excellent results. The thread length is 19 mm and the tightening torque is 25 Nm. The design is single-electrode, due to which the service life is noticeably reduced. The average cost is only 140 rubles.

• The price is available to every car owner;
• Counterfeiting on the market is minimal.

• The minimum spark gap reduces the power of the spark produced;
• The ventilation of the spark gap is reduced due to the work of the central electrode, which is "recessed".

Bosch FR7LDC Plus (0 242 235 668)

An excellent alternative to classic candles, and all because Bosh FR7LDC + (0 242 235 668) is a two-electrode spare part. The quality of the product is high and compares with many leaders in this range.Yttrium is added to the composition of the material of the central electrode, which guarantees resistance to spark erosion, which means it raises the resource of the product to a higher level.

The main characteristics of the Bosh FR7LDC+ (0 242 235 668) are similar to those from Beru. The price fluctuates around 160 rubles.

• Decent resource;
• The parameters match most regular candles.

• Often fake.

NGK BKR6EK (2288)

Parts from the Japanese manufacturer have stable sparking, have excellent resistance to the appearance of chemical deposits and are famous for high-quality work at high voltage. But the main thing is that the candles are original, and not a Chinese fake, otherwise disappointment will be inevitable. The service life of the device is high. The average price is about 210 rubles.

• There are no problems with the acquisition, it is sold in many outlets.

• The number of fakes is high;
• At the side electrodes, rough stamping is observed.

Denso PK20PR-P8

The Japanese manufacturer creates its product from platinum, which provides it with an honorable place in the ranking of quality goods. Another lure for buyers is the best price. The performance characteristics are excellent: thanks to the platinum coating, a long service life and excellent quality are ensured.

In conditions where there are increased loads, Denso PK20PR-P8 guarantees the continuous operation of the ignition system. In the model, the surface treatment of the case is impeccable, and the contact output pleases with its perfect matte surface.

• High quality;
• Long resource.

• Dimensions of the interelectrode gap.

NGK BKR6EIX (6418)

Model NGK BKR6EIX (6418) has an iridium electrode. The device is distinguished by the highest and stable sparking. It also has good resistance to chemical deposits that may occur during operation. Gives high-quality functionality at high voltage.

NGK is famous not only for supplying the finest factory-quality products, but also for being used in the legendary Formula 1 when fitting cars with spare parts.

The resource of iridium candles is at the proper level and they can give out a passage of up to 50,000 km. The price of NGK BKR6EIX (6418) is quite high and reaches 530 rubles.

• Stability in sparking;
• Amazingly long resource;
• A car equipped with such candles simply flies.

• The price is not affordable for everyone.

Brisk Premium LOR15LGS

The Brisk Premium LOR15LGS pleases motorists with brilliant performance and engineering that is not quite typical. The shape of the side electrodes of this device is unusual, but the fact is that they “look down”, that is, they are lowered along the rod. Because of this, the sparks produced "surround" the main electrode along the entire length of the exposed part. Due to this, the fuel-air mixture is ignited at the primary stage of supply to the combustion chamber. This action saves fuel well, which is a definite plus for any driver. The price is about 700 rubles.

• Non-standard form of electrodes;
• dense spark;
• Fuel economy;
• Long operation.

• "Bite" cost.

Beru Ultra X 49

Beru Ultra-X 49 is manufactured by a German company. The difference between these candles and others is that the side electrodes are asymmetrically located: two of them are separated by 0.8 ml from the rod, and the rest are at a distance of 1.2 ml. This provides competent support for sparking, regardless of operating conditions.

An additional advantage is that Beru Ultra-X 49 is compatible with gas sources.
It costs about 600 rubles.

• Operates on liquefied natural gas;
• Fuel economy at altitude;
• Even if there is a lot of pollution, the spark is stable;
• Excellent value for money.

• The percentage of power increase, in the case of an open damper, is low.

Bosch WR7DP

The German manufacturer has created a unique device of its kind, since the core of the central electrode with a ceramic insulator spews an original spark in the form of a small fiery discharge. The generated discharge has amazing stability, no matter what the voltage is in the network of the machine.

If the car is refueled with high-quality fuel, then the resource of one Bosch WR7DP reaches 55-60 thousand kilometers. Platinum coating plays an important role in this. But it is worth considering such a factor as roads. And they sometimes have a sad effect on spare parts, forcing them to use up resources faster.

Average cost - 250 rubles

• State-of-the-art central electrode design;
• Optimum ratio of quality and price;
• Arc of a spark in the form of a plasma form;
• Stability is ensured at any voltage;
• Modifications are suitable for cars such as Chevrolet, Renault, VAZ, etc.

• Fuel is consumed a little more than with conventional regular candles.

What to choose anyway?

When the old candles have completely used up their resource, you can make a mistake by purchasing the first spare parts that come across on the market as a replacement. This decision will be fundamentally wrong, since it is worth focusing on parameters such as size and glow number.

As for the size, if it turns out to be too small, then there will be problems with screwing the device. The electrodes simply will not be able to reach the combustion chamber. If the size is large, then a new problem will appear, since the candles will “creep out” of the place. In addition, the piston will hit the electrodes, and this is fraught with engine damage.

And now let's go through the heat number. What it is? This is the name of the value that indicates to us the time after which the device will reach the state of incandescent ignition. That is, the glow number is a kind of indicator of the thermal operation of a candle. If the number reaches high values, then the candle becomes colder, which means it may well function with high temperatures. And if the number is low, then we have a hot candle at the output, which quickly overheats.

Therefore, before purchasing candles, you should read the instructions for the car, because analogues are indicated there.
