In order for the fuel-air mixture of the engine to ignite perfectly, a stable spark is needed at the right moment. Therefore, the right choice of spark plug is essential for optimal combustion and performance development of the engine. Special attention should be paid to the thermal value according to the manufacturer's specifications. Since each manufacturer specifies the thermal value differently, a Bosch thermal value of 3 may correspond to an NGK value of 9, for example. In every vehicle manual, the manufacturer's specifications are listed together with alternatively usable spark plugs and their exact designations or type codes.

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

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