Best plugs on a 3100 with a 75 shot wet

[blackbombshell95]

Stock heat range should be fine. Price of the plug doesn't matter.
And should I close the GAP a bit? What is the stock gap? Copper? iridium?

Application is a 1995 GP 3100


I'm going to a local BOP(buick olds and pontiac) gathering / race this saturday and i'm shooting for a 14.99. I'm gonna try and fab FWI on friday.

As of now i did a best of 15.4 on 55 shot.

1 more thing, can a 95 3100 UIM TB side be opened up to match a 62mm TB?

denso.. and you would have to sleeve the TB to do that if its even possible (i dont know what the older ones are like)

What kind of denso plugs? Iridium? Currently i have denso iridiums @ stock gap/heat range

ya know what forget it. I'll just pull the plugs first and then go from there instead of posting like an idiot. They could be fine for all I know. only got 20k miles on them.

yeah, those are my favorite plugs.. ive known boosted guys running 50+psi on them for more than a few runs down the strip
