Function like the stock setup 2. make a better sound than the stock setup. 3. look good.

This is what I came up with. It is heavy gauge stainless steel (#7 polish) and will allow for use of the stock panel filter, or a K&N cone. Video clips and process photos to follow soon.

The open filter systems that I've seen, all suck the 'hot' engine air. I've seen estimates that for every 10 degree drop in temp, an engine can gain 1hp. How true that is for out cars, I do not know. I'm not all that concerned either to be honest, but that theory still applies I guess. Air is more dense as it gets colder.

btw what cad program were you using, and what did you use for the programing of the cnc?
