Ok, so I drive an 01 Mustang GT that is procharged. I push 8lbs intercooled, with exhaust, custom CAI, and a conservative tune. I am wodering what other guys run for spark plugs and if you run cooler plugs (1 or 2 stages cooler).

 

at least 1 step cooler, probably 2 for you.

 

Yea, i'm running 2 steps cooler currently. Any suggestions on what type of plug you like and which ones to stay away from?

 

autolite. copper core plain ol' plugs. They work perfectly and you have to change them about every 15K miles so you'll get periodic forced inspections of what's happening inside the chamber which is smart for a forced induction car.

I don't like spending more than 2 bucks a piece for plugs. If you are, you're spending more than you need to.

 

NGK TR6's.....1 stage colder.
