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, its tested on a flowbench. Then its tested on the vehicle. And finally, Banks density-tests the Ram-Air against stock and many competitors. Thanks to its enclosed cold-air housing, huge inlet, giant dome-shaped filter, and streamlined design, Banks Ram-Air Intake maximizes the flow of cool, dense air to the engine for greater power and fuel economy. It flows better than stock and the competition. And delivers greater air density to the turbos inlet than the stock system and every competitor tested!
