I'm new but I thought I would put this on here. I like to "do it yourself".
This intake is 100% home made. I don't know if it works like a store bought one but the 3000+ rpm is definitely stronger.

I've had it on for a couple thousand miles now. http://www.freewebs.com/arizonarider...madeintake.htm
