Spark plugs in a car have an important function - they provide a spark that ignites the fuel / air mixture. The power characteristics of the engine, fuel economy and the amount of harmful compounds in the exhaust gases directly depend on the quality of the candles.
Well-known domestic and foreign spark plug manufacturers pay special attention to the reliability and efficiency of their products. To improve the quality of the spark, precious or rare-earth metals are used, the shape and configuration of the electrodes, as well as the gap between them, change. A wide range of spark plugs allows you to choose the optimal solution for any car, regardless of engine type, brand, model and year of manufacture.
