Testing, testing & more testing.

Banks Ram-Air Intake Systems are tested and proven. They start out as CAD software prototypes and are put through flow simulations. After a hardware prototype is made, it's tested on a flowbench. Then it's tested on the vehicle. And finally, Banks' density-tests the Ram-Air against stock and many competitors.
