Banks Power Ram Air Intake System
2001-2004 6.6L LB7 GM Duramax
Passes the test. Again and again.
Others build and ship without testing. Not Banks. Their 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!
Filter on a stick: a joke that’s not funny.
A filter on a stick is a bad joke. It’s wide-open to hot underhood engine air, and there’s no power in hot air! There's a reason that the OEM's use enclosed airboxes, THEY WORK! Ram-Air houses a giant lifetime filter in an enclosed cold-air box, which inhales cool, dense outside air—more than Banks’ competitors and up to 57% more than stock—for more power and mileage, lower EGTs and less smoke.
Bellows, too? Very exclusive.
Banks Ram-Air is the only aftermarket intake with bellows. This accommodates engine movement and prevents component damage for longer service life.
