Spark Plugs?

Just wondering what plugs some of you guys are running with your 99+ 4.6l Mustangs, and what gap? and pro-charger....

Autolite 764's I beleive are what we are running in a friends car... 2 steps colder than stock and they are gapped at .035 with spark blow-out now that his MSD took a crap and it's bypassed. He is getting another MSD, but in the mean time I am going to try a .028 gap on it to see what it does. That is what most people are running on here with great success... between .025 and .030.

We usually run NGK TR6 plugs gapped at .030-.035 for all of our stret based 4.6L cars.

IMHO the best plugs I've used on my cars and friends' cars are the Motor Sport Plugs part # AWSF 22C which are a one heat range colder than stock. I've used them on every car I do the install on and they are perfect. I usually gap them at 0.35. I just had to gap them to 0.28 on my buddy's car because anything more than that and it will blow out the plugs.

Hope I helped.
