which plugs are the best

scurr3165 · 03-13-2002, 03:57 PM

I have a fairly stock mustang with a few bolt ons, which type of plug works best and I won't have to change every 15,000 miles.

Bolt-ons:
1) underdrive pulleys
2) 3.73 gears
3) k&n filter
4) crane ignition system

I use AutoLite Copper - #3924 for my Trick Flow heads. I think you'll want to use #3925's for a stocker. Can someone confirm?
