In order for the gasoline-air mixture of the engine to ignite perfectly, a stable spark is needed at the right time. Therefore, the correct selection of spark plugs is essential for optimal combustion and performance development of the engine. Special attention should be paid to the heat value according to the manufacturer's specification. 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 reference, each vehicle manual lists the manufacturer's specifications with alternative applicable spark plugs and their exact designations or type codes.

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

Be cautious when using suppressed spark plug boots; 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.
