In order for the fuel-air mixture of the engine to ignite perfectly, a stable ignition spark is needed at the right time. Choosing the right spark plug is therefore essential for optimal combustion and power development of the engine. Particularly 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 may correspond to an NGK value of 9. For orientation, the manufacturer's specifications with alternatively usable 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.

Beware when using suppressed spark plug connectors; double is not necessarily better; in this case, no suppressed spark plug should be used, as the total suppression resistance would be too high.
