Airforce One Performance Intakes are designed from the ground up for absolute performance, quality and longevity. These systems use aviation grade stainless steel polished to a mirror finish that will never rust or corrode regardless of the climate the system is exposed to. Custom designed and molded Hi-Temp stabilized composite adapter boots, couplings and MAS airflow venturi adapters are used. The venturi adapter generates a high vacuum in the filter enabling the filter to draw a higher volume of air while naturally lowering the ambient incoming air temperature by several degrees, eliminating the need to enclose the filter in a box and substantially increasing horsepower. The Power Stack Filters are sized to each system and carry a lifetime warranty.
