installed k&n cold air intake saturday what a pain that was very diffacult to do for a dam intake if you ask me. but to get to the point i love it the whine it makes is incredible so dam loud also i can feal a little differnce in performance. i took it out that night and won 2 races taht i raced againest a rsx and gt mustang and both of them ask me if i had a bigger supercharger on it. also i got no cel and the last 3 days it been below 32 degrees so hopefully it stays off.
