I have looked for a cold air box...Grandpa Bob turned me onto this wizard type out in Carson City Nevada. His name is Guy Light and he does custom fabbing and I pretty much was blown away with his skills. I am getting one done next week. He just built a brand new Acura RSX for some guy spec'd for production class SCCA rally, rim of the world rally this week. 70000$ worth of offroad weaponry. Guy is good- I'll ask him if he would be interested in producing a few more off the spec of mine. Some insight- he said using the stock aperture on the side was inefficient, as the vortex from the wheel spin actually would draw air out/away from the box, so he suggested having the air box aperture come from the front grill (ala rally style)taking advantage of the air pressure into the radiator- fyi...
