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 Hood Vents help channel out excessive heat that builds up in the engine bay . Built using pre-preg. carbon fiber reinforced polymer (CFRP) composite materials for superior strength-to-weight ratio, APR Hood Vents 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). Install: Please have a professional body shop install. Cutting of the hood is required. Please protect it when cutting so it does not rust in the future. We are not responsible for damages done to your vehicle. Please do at your own risk.
