NGK Spark Plug Set 2x Lmar8ai-10 Iridium Resistor 26,5mm Long Thread 10mm 94319

Heavy Tuned In order for the gasoline-air mixture in the engine to ignite perfectly, a stable spark is required at the right time. The right choice of spark plugs is therefore essential for optimum combustion and engine performance development. Particular attention should be paid to the manufacturer's specifications when it comes to the heat value.

Since each manufacturer reports the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9.
