I have a 2002 mustang GT. with all the basic bolt-ons. But no type of forced indusction or nitrous. My car is also SCT tuned with advanced timing blah blah blah. Do you think that the NGK tr6 (copper, 1 step cooler spark plugs) are the way to go for my car? what do YOU think they should be gapped at?

 

they should be fine, Im not a big fan of NGk's
I'd go .048 to .052 for the gap
