Form and function are perfectly blended in this fiberglass Ram Air Hood. The sporty lines and assertive look of the center scoop give the F-150 a distinctive look while the functionality of the scoop allows cool air to be channeled into the engine compartment just over the factory air box. Cool air is more dense and burns more efficiently than hot air and can improve both power and efficiency. (Hood pictured in fiberglass with a carbon fiber blister)
