Tomorrow I'll be putting my 2.6" puley on and 60's and getting it tuned. I don't know if I have the right spark plugs for this, right now im using the autolite copper core ones that came with my intense stage 3 kit are these good?

 

Most people suggest 1 step colder plugs than stock.

If the plugs came with the kit and is from Intense, then I'd say you would be fine.

 

Thanks, yeah they are 1 step colder

 

Make sure you gap them down to about 0.35". I don't think they come pre-gapped.

 

I have a 2.6" pulley with the autolite coppers and my car runs fine. I bought my plugs from napa, and they came pre-gapped to .35"
