Man, keeps alot of the stock set up? For $400? I'll pass. We were all told by the guys doing some hard-core development on the Redline, that the stock intake system is pretty good. I'm having a little trouble swallowing $400, a 17hp gain, for a system that retains alot of the stock pieces. There are only 3 stock pieces to begin with. The rubber tube from the supercharger to the airbox, the airbox, and the little tube that comes out from that. Is there a new MAF sensor as well? If there isn't, or if it's the same as the stock one, it's gonna need to be swapped out with one as soon as you modify much else on the car. This sounds like someone cornering the market as the first player, thinking people are dumb enough to buy-in.
