2008-2014 Subaru Impreza WRX and STi – APR Performance Carbon Fiber Brake Cooling Ducts
The APR Brake Cooling Ducts are designed to maximize the flow of air with their aerodynamic shape. This is known as “venturi effect“ and works by increasing pressure and speed when the vehicle accelerates, creating a suction that channels more air through the ducts from its larger frontal opening into smaller pipe sections. When combined with appropriate high–temperature hoses (not included – you must buy these separately at your favorite racing supply store), they will help keep brakes cool lap after lap on track days by delivering large amounts of fresh cooling air.
Excessive temperatures can cause major and costly harm to essential parts of a car. To help move away the additional heat, engine bays, radiators, brakes, transmissions and differentials all have to be provided with good ventilation. APR Air Ducts bring fresh cooling air into areas that need extra chilling. Manufactured from pre–preg carbon fiber reinforced polymer (CFRP) composite materials for remarkable strength in comparison with its weightiness; APR Air Ducts add both practicality as well as lightness where it matters most.
