For the gasoline-air mixture of the engine to ignite perfectly, a stable spark plug is needed at the right time. Therefore, the right choice of spark plug is essential for optimal combustion and engine performance development. Special attention should be paid to the heat value according to the manufacturer’s specifications. 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 specifications with alternatively usable spark plugs and their exact designations or type codes.

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

Caution applies to the use of suppressed spark plug connectors; double is not always better; in this case, a suppressed spark plug should not be used as the total suppression resistance would be too high.
