In order for the fuel-air mixture of the engine to ignite perfectly, a stable spark is required at the right moment. Choosing the right spark plug is therefore 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 indicates the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9. For reference, the manufacturer's specifications with alternative spark plugs and their exact designations or type codes are listed in every vehicle manual.

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

Caution is advised when using suppressed spark plug connectors; double is not necessarily better; in this case, a suppressed spark plug should not be used, as the overall suppression resistance would be too high.
