In order for the fuel-air mixture of the engine to ignite perfectly, a stable spark must occur at the right moment. Therefore, choosing the right spark plug is essential for optimal combustion and performance development of the engine. Special attention should be paid to the heat value according to the manufacturer's specifications. Since each manufacturer specifies the heat value differently, for example, a Bosch heat value of 3 can correspond to an NGK value of 9. For reference, the manufacturer's information with alternatively usable spark plugs and their precise designations or type codes is listed in every vehicle manual.

We work with official vehicle application lists from manufacturers and offer you exactly the right spark plug for your vehicle.

Be cautious when using suppressed spark plug connectors; double is not always better. In this case, no suppressed spark plug should be used, as the total suppression resistance would be too high.
