APR Brake Cooling Kit 2018-2021 STI
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
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).
