To ensure that the gasoline-air mixture in the engine ignites perfectly, a stable ignition spark is required at the right moment. Choosing the correct 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 represents the heat value differently, for example, a Bosch heat value of 3 may correspond to an NGK value of 9. For orientation, each vehicle manual contains the manufacturer's specifications for alternatively applicable spark plugs along with their exact names and type codes.

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

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