Banks Power 2011-2012 GM LML Duramax 6.6L Ram-Air Intake System

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.

Proven design. Proven performance.

Banks Ram-Air Intake maximizes the flow of cool, dense air to the engine for greater power and fuel economy. Thanks to its enclosed cold-air housing, huge inlet with giant dome-shaped filter, and streamlined internal design, it flows 35% better than stock! In fact, it performs so well that it delivers greater air density to the turbo’s inlet than all competitors tested.

Longer service life, too.

An aftermarket exclusive: with 5″ bellows, Banks Ram-Air accommodates engine movement, which protects the components and extends service life. What’s more, Ram-Air is designed to not cause fault or error codes.

It’s all about density.

And Banks Ram-Air Intake delivers. The harder you work your truck, the more Banks Ram-Air Intake improves power and fuel economy!
