APR Performance Carbon Fibre Brake Rotor Backing Plate W Hose Enfermedades Mentales en EL DSM V: Criterios y Caractersticas. ****Does not fit 2008 UP WRX(Non STI)*** 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. 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).
