Build it better. That is the American ingenuity behind AIRAID. Founded in 1997, AIRAID started development on intakes for trucks and SUVs. AIRAID Premium Filters consist of multiple layers of cotton-gauze plus one layer of synthetic fiber material sandwiched between either stainless steel or aluminum mesh, depending upon the application. The casing of the filter is hand-poured urethane, which offers superior performance and durability, and will not shrink or crack from prolonged heat exposure under the hood. Over the years, AIRAID Filter Company has become the recognized leader in air management for both gasoline and diesel power plants. Extensive research and development has allowed AIRAID to come to market first with high quality products that improve drivability and performance.
