What is the Napa 6637 intake, or DIY intake, etc. I see listed on people's signatures? I think it's pretty dumb to pay $230 bucks for a foot of pipe and a filter, so what is a better, cheaper route? Thanks! Info and pics appreciated!

its a BIG filter, that you basically take a 4" peice of exhaust pipe and adapt it from your stock plastic intake to the backside of that filter. it flows well, and is really cheap. 6637 is the part number. its about 40 bux for the filter IIRC.
