Okay, I have two sets of plugs for my engine. Both Champion. One has what I believe is called a projected tip. The other set does not. There is no likely hood that the projected tip will be hit by anything. It's a low compression engine (more or less 7-1). So the question is... Assuming the same heat range, any benefit from using the projected tip vs the regular tip? (these are the old plugs and I'm getting ready to get a new set)
Thanks:
Paul
