For customers that purchase the APR cooling ducts without the hoses and backing plates and later decide they want to upgrade, these are the components that will turn it into a full cooling package.
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 (included), 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. 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.
