Brakes slow your car by turning friction into heat, help remove more of that heat! These are the largest brake cooling ducts available for street use, they come from the European 911 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 and they fit '98-and-up 911, and all Boxster and Cayman. Note- you need to be running a 18" or larger wheel with these ducts.
