I think by far the best mod that I have done yet. Noticeably more responsive, especially in 3rd. 3rd pulls just as much as 2nd, seriously! lol Also, my exhaust sounds much better? How the hell does that work? Colder air = better air/fuel mixture? Meh, not sure but in 1st/2nd when i give it some and change up it lets off a HUGE backfire and sounds 100% awesome. Cheers riko babay! Had to cut it up a bit, and shorten the 45mm tube coming off of the cooler, and had the clean all those wasp's out of it! (I counted 10 plus!!!!)
