Brakes slow your car by turning friction into heat, help remove more of that heat!! This is the largest brake cooling ducts available for street use, they come from the European 996 GT2. A two piece duct, consisting of a hard plastic securing base, and a more flexible scoop on the bottom. On some applications, the wheel well liner or duct may have to be modified due to their large size. These are the largest air ducts available for a street car.


Length: 20.5 inches

Height: 6.5 inches in the center

Your old duct can be easily unclipped, and then the new ducts will clip into place. No bolts or other fasteners are necessary, the A-Arm clips will secure each duct. On some some applications, an additional rivet can be used (but is not required).
