sparkplug gap for tr55
 

what gap u guys running for the tr55's?

The tr-55 comes pre-gapped. If you're pretty much stock or have a few bolts on, just leave em. If you have a turbo or blower, I'd run the tr-6 with a .35 gap. That's what I used to have on my truck when I had the radix. When I sprayed it, I ran tr-7 plugs gapped around .27-.29 on 9#'s

thanks will do.

I run mine at .055, and the general consensus is anywhere between .050 to .060. Be sure to at least check the gaps before you install them, last time I bought a set of TR55's 7 of them were around .055 or whatever, and one must have been dropped as it was at .040ish...

.055 here when I was N/A
