Our Ram Air Intakes start out as CAD software prototypes and are put through flow simulations. The design is refined until the simulation shows optimal performance. Then a hardware prototype is made and the design is validated on a flowbench. After that comes dyno testing and on vehicle testing. It takes a superior design to pass all those tests! A filter on a stick is a bad joke. It's wide open to hot
