"Cold" RACE cylinder head spark plug

If your normal RACE spark plug tends to "knock", do not hesitate to opt for a colder one, which will be able to withstand the higher performance of your engine.

WARNING: This spark plug can only be used with RA-ce cylinder heads and not with normal cylinder heads, which use "normal" spark plugs.

Note: This spark plug must be fitted with a small spark plug cap (see related products) because the olive of the cold spark plug cannot be removed.
