For the petrol-air mixture of the engine to ignite perfectly, it requires a stable spark at the right time. Choosing the right spark plug is therefore essential for optimal combustion and performance development of the engine. Special attention should be paid to the heat value according to the manufacturer's specifications. Since each manufacturer defines the heat value differently, a Bosch heat value of 3 may correspond to an NGK value of 9, for example. For reference, each vehicle manual lists the manufacturer's specifications for alternative 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.

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