It is a proven scientific fact that cold air is denser than hot air, which means that an engine breathing cold air is going to make more power than the identical engine breathing hot air. Why? Because the denser air charge provides more oxygen molecules for more complete combustion of the atomized fuel in the cylinders, and more combustion means more power. The quest for cold air is what drives the AIRAID Cold Air Dam Intakes. The CAD Intakes retain the stock filter location but give the stock intake system a big boost with the addition of a huge air inlet that provides a steady, free-flowing supply of cold air. This is done via Cold Air Dam panels, which mount in the factory air box location and utilize any factory cold air inlet ducts that are present, while adding additional cold air passages to the filter. These panels also keep the filter isolated from the hot engine compartment air by sealing to the underside of the hood via blade-style weatherstripping. | Airaid CAD Performance Air Intake 202-129
