one step colder plugs, and she feels like a new car. I would recommend this to anyone experiencing similar problems. My car has the battle stage 2 tune, with a catted turboback, and front mount.

I think when I bought mine a while back it was like $55-60 on eBay for the set if I remember properly. Great plugs! Manic recommends them.

BRISK MR12LS are 14.99 on their site and a degree colder/ silver. If you haven't checked out their site, give it a look. Some good info on there. Maybe someone will chime in if there is a better option.
