What is the main reason for going to the surface gap spark plug against the standard type of plug. I noticed my book had surface gap plugs, but since I've had my boat (nealry 6 years) it had normal type plugs in it.

Re: Spark plugs

Surface gap plugs serve better for extended periods of high RPMs. Standard sparkplugs idle better.
