Nate, way too big of a gap for TR6. You should be TR5 gapped at .055", or TR6 gapped somewhere between 40-45 (however, you don't need 2 ranges colder, so go with the 55).

Car whoops *** with the way it'* set now....Mileage jumped up a few too...went from 24mpg hwy to 29 hwy...ZERO KR......
Think i'll leave it alone.
Why all the sudden you telling me to gap them in the 40'* now....last time we talked about my plugs everyone was talking about .50 at the smallest?

You will foul them. I speak from experience on the Zilla from the first time I ran TR6'*:

Factory gapping for us is .060". The TR55 comes that way and is fine. NGK'* website shows the TR6 gapped at .039", and I'd never noticed that before (I was re-gapping mine to .060", and this is what I called to ask them). The tech told me the TR6 is actually gapped at .032", regardless of the website stating .039".
At this point, I asked him what I should be gapping to, based on my mods. He gave me a range of .040" to .045" for the TR6 in my car, and he agreed that because of my hotter MSD coils (and the same would hold true for the 97+ SSEi coils) I should tend to the bigger side, or .045".
The general rule of thumb is never change the gap larger or smaller than factory gapping by .008". In this case, the listed gap of .039" could be safely raised to .047 for my TR6'*, but the ACTUAL gap as I was told of .032" could only be safely gapped up to .040". With that in mind, he told me I'd be fine up to .045", just pushing the PAPER limits. The idea is to keep the faces of center electrode and ground electrode as parallel to each other as possible, and if you go too far, you induce an angle on the ground electrode, so the gap isn't even across the face of the center electrode.
