No matter what you always recheck the gap on spark plugs. If they were bumped before packaging they can be off. I have never once skipped checking plug gap on customers or my cars. It only takes a few seconds to check.

I agree. Never know.

Ngk's for me have always been almost spot on. Other brands not so much. I just installed tr6's in my 355 and they were all on .035. I opened them up to .040. We'll see how that goes.
