Out of all the **** ive read on HT, I have never read about gapping plugs for FI applications.
Do you want to make the gap bigger or smaller, and how do you know how much to gap them?

You want to make the gap smaller and generally starting at .035(low boost) and moving down from there. What I mean is, you want the widest gap possible w/o misfire. Example: If the engine misfires (it will be rev-limiter style, you'll know) and the gap is at .035 then, tighten it a little to say, .032 and try that. You repeat this process until the engine does not misfire. Different setups will vary from .035-.018(Crazy tight). Cylinder pressure will be the deciding fatcor.

They have a small tool that measures the clearances.

I've seen sparkplug gap measuring tools, but he should also be able to use a set of feeler gauges right? when I got a set of plugs from the dealer I used my feeler gauges to check the gap and they were within Honda specs.
Just take several feeler gauges and stack them to check your gap. For example if you wanna make sure they are gapped at 0.28 just get your feeler gauges for 0.10, 0.09, 0.05 and 0.04 add em up and that equals 0.28.

That's what I thought. A 6 plug would be one step cooler

NGK spark plugs go backwards.. they are the only company that does this. my buddy at pep boy got the NGK book out and we look it up, in the front it shows you what each number on the plug stands for.. in most cases 4 would be hotter.. NGK 4 is cooler
