![]() Sorrry I don't think I made it very clear. The higher the number the hotther the plug, lower colder. You want a colder plug not because of engine size but whats in it. You have higher compression and a hotter cam both will allow the clyinder to fill more. This usually means going to a colder (lower number) plug. You may even get away with using a 23. I hope this clears that up
