Plug Gap
-
no more than .32. actually, the reason that you want the smaller gap is because you want a pretty small spark. why? i can't remember... but a big gap (+.35) can result in pretty nasty misfiring, i know from experience.
if you use a platinum plug, they've been known to misfire. why? because the combustion chamber is REALLY hot, platinum and iridium stay hotter longer than copper and may cause misfiring to occur. -

Don't go higher because cars with high cyl pressure will blow out the spark. -
Run .028 and you will be fine.
On my integra on pump gas and low boost I run .028-.030 and on race gas and 30+ psi I run .025.
