***THIS KIT FITS 2018-2021 MODEL YEARS ONLY ***
The APR Brake Cooling Ducts are aerodynamically-optimized to "funnel in" massive amounts of air. Also known as the venturi effect, when the vehicle speed increases, this funneled-in air increases in both pressure and velocity as it passes from the larger frontal area into the smaller pipe section of the brake duct. When matched with appropriate high-temperature air duct hoses, the APR 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.
Excessive heat can cause major and expensive damage to critical components in a car. Engine bays, radiators, brakes, transmissions, and differentials all need good air flow to help transfer away unwanted heat for your 2018-2021 Subaru WRX / STI. APR Air Ducts help bring fresh cooling air to different areas that need additional cooling. Built using pre-preg. carbon fiber reinforced polymer (CFRP) composite materials for superior strength-to-weight ratio, APR Air Ducts add both function and "lightness" where it counts.
Features:
-
Carbon Fiber Construction
This component is formed in the autoclave at high temperatures using pre-pregnated carbon fiber manufacturing processes, for high strength and low weight.
-
UV Resistant Coating
Each Air Duct is finished with UV-resistant clear-coat paint for resistance against various environmental conditions (take care of this as you would take care of your vehicle's paint finish - polish then coat with good-quality wax or synthetic protectant).
