This is a true cold air intake system that situates a Green air filter in the lower front region of the car, away from ALL engine heat. The Cool-Flo Race system utilizes an easier to install one piece design that uses 3" mandrel bent steel tubing along with a laser cut MAF sensor housing and bracketry. Other features include all tig-welded construction and coated with wrinkle black powdercoat. Fitment: MK4 GTI/Golf/Jetta 8v 99-05 MK4 GTI/Golf/Jetta 1.8T 99-05
