Factory gap is .45 but most of us are running a cooler plug(TR6) at a .30.

Thanks Dustin,

Pre 13 guys are using the TR6 as well. Supposedly it is the same heat range as the stock plug.

I'm looking for the 13 motorcraft p/n. I'm curious if Ford went to a colder stock plug for the 13.

Thanks fast70,

It appears Ford went 1 step colder for the 13 GT500 vs the 12 GT500. I believe the TR6's are the same heat range as the 22's on the 12 GT500.

If that is true, and I believe it is, I wonder why 13 guys would be putting in TR6's.........TR7's perhaps.
