For the gasoline-air mixture of the engine to ignite perfectly, a stable spark must occur at the right moment. Therefore, the correct spark plug choice is essential for optimal combustion and engine performance. Special attention should be paid to the heat value according to the manufacturer's specifications. Since each manufacturer displays 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 information, with alternatively applicable spark plugs and their exact designations or type codes, is listed in every vehicle manual.

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

Be careful when using noise-reduced spark plug connectors; double is not necessarily better, in this case no noise-reduced spark plug should be used, as the overall noise suppression resistance would be too high.
