Plug Gap

[94NDTA]

.35 is basically the max I would use on any FI or N20 application.

yeah i got it at like .029

Keep opening them up till they blow out....

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.

.028

How much boost are you running and is it just pump gas?

[PSiedTSi]

15psi pump gas

[amicheze]

see how far you can make the gap and then try running it and see what happens.

[integra_gsr98]

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.

As everyone else has said, run around .028". I had to run down to .022" on 35psi and 8000rpm to get my car not to blow the spark out. But, until you are running that much boost and stuff, keep it at around .028".

thanks guys!
