Hey guys, I need some help. I had zex plugs in my car and after reading some of th horor stories about what has happened with them, I got paranoid and ordered some NGK V-Power bkr7e one step colder plugs.

Now my question is, what should I gap the plugs for my 2.85" pulley?

Thanks in advance.

P.S-> I searched already but nothing came up!

I got a 2.9 and I run .35. Works good no probs.

I gapped mine at 0.040 with my 2.9 inch pulley. Do you have 60lb injectors with that pulley?

I have mine gapped at .033. That being said...I had to test about 4 different gaps to find what my car likes best. What I have heard is that you want the largest gap that your car will run with, and you should be able to go somewhere between .040 and .030. Personally I would start around .037-.040 and start dropping gap untill it doesn't run better when you go a little smaller, then go back to the previous gap.
