Here, you are looking at the APR Carbon Fiber Brake Ducts. These have been aerodynamically-optimized to funnel in massive amounts of air that creates a venturi effect to bring in more cooling efficiency to your front brakes. When matched with appropriate high-temperature air duct hoses (not included in some applications) the ARP Brake Cooling Ducts will help to channel in large volumes of fresh air to help cool down red-hot brake rotors lap after lap on the track.
