I have developed the ONLY TRUE cold air intake(patent pending) ALL others are either a variation of an open air system or it's a closed system made of uninsulated METAL - conducts heat. Mine is made of insulated 1/4 inch insulated plexiglass and seals to the hood as well as the fender side. It uses a 3" insulated plastic polimer tubing from the K&N down to the turbo and is as easy to install as taking out your stock one!! Check it out!
My air comes from the fender hole and a functional Lund hood scoop.Go to
