GMC Envoy Hood Scoops, Window Louvers

An air vent on the GMC Envoy bonnet that enables flow of air directly to the engine compartment is called a GMC Envoy hood scoop or a bonnet scoop. If the GMC Envoy vent is closed and doesn’t actually carry the air to the engine compartment it serves only a decorative purpose. GMC Envoy Window louvers are framed openings in the window, fitted with fixed or movable horizontal members for admitting air and light and keeping the rain out. GMC Envoy Window louvers can be fitted on to your car window. Window louvers give your car a great stylized look.
