I need to know if spark plug type (copper vs. platinum) and gap affects HP. My stock gap is recommended at .039-.043. I have a n/a 3.0L V6 10:1 compression wide open exhaust ram air adjustable FPR and stock ignition.

i just need to know the best type and gap for optimum HP. Let me know if you need any more info.

I know this is a hard question to answer but I figured anyone with dyno experience would know the general rules for gap/type.

Thanks. I think before I hit the track again Ill get a set of coppers and throw them in at .043.
Even 1HP is better than nothing.

Thanks again for the info.
