Chamion "Truck Plugs" Spark PLugs
Hey all, quick question.
My cousin is changing out his plugs & wires on his chevy whiled he's replacing his headers and asked me a question that I'm a little stumped on.
THe regular champion platinum plugs have a gap of .45 but he was looking at a set of the Champion Truck PLugs and these have a gap of .70...both are "OEM Replacements" for his truck. I have .45's in mine and were running fine....70 seems a little excessive on the gap.
Even the Chilton's Manual states a plug gap/reach of .45. Why are the champion truck plugs .70? Would there be any adverse effects if he went with the truck plugs & a gap of .70.
