Motorcraft AGSF-22-C which is 1 heat range colder than stock....stock is a AGSF-32-C
OK, the original question was:
"what spark plugs is everyone running in their 4.6's".
Soooo...
Randy (correct me if I'm wrong) this means you are running 1 range colder plugs in YOUR car, not necessary suggesting that this is the answer for EVERY car, right?
OK, I'm done.

Just to be sure, are you asking us to suggest what plugs YOU need in your particular car?
Or answer your question and tell you what we're running in our OWN cars (which plugs may vary depending on the equipment and build of the individual car)?

i dont think simple bolt ons are going to make the difference in a plug, i was just curious what everyone else was running with a next to stock setup like mine, thats all! thanks!

when my car had the "basic" bolt-on's, yes. then when I switched to Nytrous, I went to a AWSFA-12-C which is 2 heat ranges down....now I run a Champion "race" plug which is @ 6 steps down from the stock heat range...you wont sea any real HP increase from a colder plug, just less chance of getting into detonation, now indexing them might gain 1 HP but for most street cars, indexing can be $$

OK, that's how I've always looked at it. Y'know, I'm sort of surprised there is SO much discussion about exhausts on these cars, and so little about plugs.
Guess those topics are old school nowadays.
Thanks as always. You're a mensch to share so much!
