Service life and interchangeability of NGK spark plugs
Content
Consumables in a blue box (Iridium IX) are suitable for older cars. In this series, the manufacturer uses a thin iridium electrode, so the devices practically do not miss ignition, are effective at any time of the year, reduce fuel consumption and improve vehicle acceleration.
During scheduled maintenance of the car, it is necessary to check the condition of the candles. And after 60 thousand mileage, these consumables are recommended to be changed. The service life of NGK spark plugs depends on the intensity of travel and operating conditions. Untimely replacement threatens with engine malfunctions, loss of performance and increased fuel consumption.
Parameters of spark plugs "NZhK" France
These parts are manufactured by NGK Spark Plug Co. The company is headquartered in Japan, and factories are located in 15 countries, including France.
Устройство
Spark plugs are needed to ignite the air-fuel mixture. All models work on a similar principle - an electric discharge occurs between the cathode and anode, which ignites the fuel. Regardless of the design features, all candles function the same. In order to correctly choose a candle, you need to know the specific brand of car, use online catalogs, or entrust the choice to a technical center specialist.
Features
Candles for engines are produced with two types of markings:
The 7-digit character number used for the NGK SZ encrypts the following parameters:
- hexagon thread diameter (from 8 to 12 mm);
- structure (with a protruding insulator, with additional discharge or small size);
- interference suppression resistor (type);
- thermal power (from 2 to 10);
- thread length (from 8,5 to 19,0 mm);
- design features (17 modifications);
- interelectrode gap (12 options).
The 3-digit code used for metal and ceramic glow plugs contains the information:
- about the type;
- incandescence characteristics;
- series.
Candles can be distinguished visually, because the design of the models is different:
- by type of fit (flat or conical shape);
- thread diameter (M8, M9, M10, M12 and M14);
- cylinder head material (cast iron or aluminium).
When choosing consumables, pay attention to the packaging.
SZ in yellow boxes is used in assembly line and installed on 95% of new cars.
Black and yellow packaging (V-Line, D-Power series) is applicable for products made from precious metals and using the latest technologies.
The silver packaging and the Laser Platinum and Laser Iridium series belong to the premium segment of the NLC. They are designed for modern cars, powerful engines, as well as for economical fuel consumption.
LPG LaserLine in a blue box are designed for those who decide to switch to gas.
Red packaging and the NGK Racing series are chosen by lovers of speed, powerful engines and harsh car operating conditions.
Interchangeability table
The manufacturer's catalog contains information on the correct selection of candles for each modification of the car. Consider the options for purchasing consumables using the example of Kia Captiva in the table
Model | Model of a candle installed on a factory conveyor | It is recommended to install when transferring the engine to gas |
Captiva 2.4 | BKR5EK | LPG 1 |
Captiva 3.0 VVT | ILTR6E11 | |
Captiva 3.2 | PTR5A-13 | LPG 4 |
From the catalog of the manufacturer NGK you can find out about the interchangeability of consumables of different brands. For example, BKR5EK, which is installed on Captiva 2.4, can be replaced with analogues from the table:
NGK | Replaceability | ||
SKU | Серия | BOSCH batteries and motors | CHAMPION |
BKR5EK | V line | FLR 8 LDCU, FLR 8 LDCU +, 0 242 229 591, 0 242 229 628 | OE 019, RC 10 DMC |
All NZhK consumables are manufactured according to industry standards. Therefore, instead of SZ of this brand, you can purchase analogues from the same price segment (for example, Denso and Bosch) or something simpler.
Authentication
Counterfeit NLC products can be visually identified by the following features:
- poor quality packaging and labeling;
- no holographic stickers;
- low price.
A close examination of a homemade automotive spark plug shows that the o-ring is very weak, the thread is uneven, the insulator is too rough, and there are flaws on the electrode.
Replacement interval
Candles are checked during scheduled maintenance and changed at a run of more than 60 thousand km. If you install the original, then its resource is enough to start the car even in the coldest winters.
Life time
The warranty period for candles with active use is 18 months. But consumables are stored for less than 3 years. When buying, pay attention to the marking of the production date and do not purchase last year's SZ.
NGK spark plugs do an excellent job of starting the engine, with a lifespan long enough to last several seasons.
