If your car is a 99-04 I recommend always using OEM plugs. Don't want to strip the threads in the heads.

I run NGK laser iridium platinum plugs and love em but the grand total for just the plugs did come to be over $100 and I'm also running with an MSD ignition box and Pro-billet distributer

If you search on line almost every tuner runs NGK plugs on N/A cars and cars with boost. If your has no power adders run NGK tr7. I am supercharged and run around 15lbs of boost and use the TR6 with the gap closed up. I have never had one issue with them. The TR6 are 1 degree cooler and are what they call a V-power plug. Motorcraft stock plugs are decent. AVOID Bosch plugs plugs period. The auto light plugs were decent in the old Fox body pushrod motors.

Re: aftermarket plugs

I use NGK Iridium IX's.. guess I'm part of all the rest of the guys out there, but they work very well. I've never had problems with them and run them in multiple vehicles along with MSD coils. I highly recommend them. No need for a racing plug or a "hotter/colder" plug until you actually need it.

I Just got a motorcraft plug to throw in when I change the coil on my #4 cylinder. Now that I read this I think I should I've gone with the iridium sounds better but motorcraft should do the trick

Re: aftermarket plugs

sounds like a toss up!

actually, i did call bama, and the fella i spoke to suggested their tunes might benefit most from plain old (copper) motorcraft/autolite plugs?! kind of surprised me, but hopefully true... could always use the extra scratch for the next mod!
