For the fuel-air mixture of the engine to ignite perfectly, a stable spark must be generated at the right moment. Therefore, selecting the right spark plug 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 denotes the heat value differently, for example, a Bosch heat value of 3 can correspond to an NGK value of 9. For reference, every vehicle manual lists the manufacturer's specifications along with alternative compatible spark plugs and their exact designations or type codes.

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

Caution is recommended when using resistor spark plug connectors; doubling is not always better; in this case, no resistor spark plug should be used, as the overall resistor would be too high.
