In order for the fuel-air mixture in the engine to ignite perfectly, it requires a stable spark at the right moment. Therefore, the right spark plug choice is essential for optimal combustion and power development of the engine. Special attention should be paid to the heat value according to the manufacturer's specifications. Since each manufacturer lists the heat value differently, for example, a Bosch heat value of 3 can correspond to an NGK value of 9. As a reference, the manufacturer's specifications with alternatively applicable spark plugs and their exact designations or type codes are listed in each 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 always better; in this case, no suppressed spark plug should be used as the total suppression resistance would be too high.
