That would depend on your mods.

I use NGK TR6 iridium gaped at 35.

The reason I use Iridium, is because of the spark failure test.

This is a chart to help you decide what gap.

THANKS! Ok one more. Do I gap it based on my max PSI? I push 14-16 when I get on it.

That chart is not an exact science. It's just a guide line to get you close. I run a higher compression so my gap is different.

And yes max boost.

I would go 32 to 34 if I where you.

One point of interest. The smaller the gap on the iridium, the more idle issues you will have.

Cool, Thanks again. I'm just having issues on start up with missing until she warms up and I'm hoping that plugs will fix it. Anyone sell NGK locally?

i work at autozone and we got em. Parts Sales Manager, part time, while full time student.

of course, im down in Waco, for Baylor, but just throwing my place of business and employer in the mix...


it may be different up there but around here, like all of waco, hates going to o'reilys, for teh most part. They are very lazy and do not want to do the small tasks like CEL or replacing a battery for a lady, hell, even for the guys that come in and cant replace their own damn battery...:hammer:
