When considering improvements to the cooling performance of your vehicle, one of the primary factors is to take into account is aerodynamics. Although many vehicles do have large intakes, the large opening of the upper area behind the grill lets the air escape and does not have the desired cooling effect on the radiator.
The Greddy Air Diversion Plate, made from 1mm Aluminum and embossed with the GReddy logo closes off the open area behind the grill, attempting to make sure the incoming air is guided to the radiator more effectively. At the same time, the apperance of the panel has been described as adding to the cosmetic appeal inside the engine bay.
