[QUOTE="PM-Performance, post: 16397736, member: 176806"] The gap really doesn't have to do as much with the plug type and more for boost levels. I would say under 20PSI .028 is fine. If it blows out for some reason, just tighten the gap a little. There really is no ill effect of running too tight a gap, other than maybe replacing plugs a little sooner. It sounds like most replace atleast once a year anyway. Too open a gap will cause blowout though and that just sucks. [/QUOTE]
