Frequently asked questions

Is the equivalent exactly the same?

An equivalent has the same dimensions (thread, reach, hex size) and a similar heat range. Heat range scales differ between brands, so the match is approximate.

What does the number in the code mean?

The number shows the heat range. For NGK a higher number means a colder plug; Champion and Denso use different scales.

The code is not found – what now?

Check the spelling or search the code directly in the shop. You can also write to us and we will help you find the right plug.
