What coil packs are you running?

I prefer Brisk plugs but have used NGK Iridiums with success. 1 Range colder works for me. I run .035 with hi-output coils. I have not tried larger gaps.

NGK BR7EF's, gap them at .018 and see how it works.

I just switched to NGK B8EFS at .020. Use to run the 7's at .020 but they looked hot when I checked them last...25-29lbs.
