N/A spark plug gap for IKH20 iridiums?

[cmart357]

So the stock gap is .44 from what i have searched here for stock plugs. Boosted guys are gapped .32 or .35 for the iridiums. What about the N/A iridiums? Stock gap of .44? Could not find any info searching here the site.

The proper gap is .039" - .044"

If you do not have the proper type of gapping tool I suggest just installing them as the come out of the box. That should .032"

I have a set of feeler gauges I can use. So the tighter gap on the sc trucks is for stronger spark due to the boost? Thanks Gadget.
