Flowbench developed, dyno proven cold-air intake with enclosed housing improves flow up to 57%; increases power and fuel economy; reduces exhaust gas temps and sooty, black smoke.

Testing, testing and 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.

Proven design. Proven performance.

Thanks to its enclosed cold-air housing, huge inlet, giant dome-shaped lifetime 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 35% better than stock. And delivers greater air density to the turbo's inlet than the stock system and every competitor tested! Air density is the key to better performance.

More density = More MPG and HP

Banks Ram-Air Intakes deliver. The harder you work your truck, the more Banks Ram-Air Intake improves power and fuel economy! Longer service life, too.

The Banks Ram-Air Intake System delivers exceptional airflow and air density. Its large cotton gauze air filter requires fewer cleanings than competitive filters (stock's small paper filter is not reusable). With its giant 7-1/8 inch outlet, streamlined components and enclosed cold-air box that keeps hot engine air out of the intake, the Ram-Air flows up to 57% better than stock. Improves power and fuel economy; lowers exhaust gas temps and reduces black smoke. (An indicator of unburned fuel, black smoke is power you can see but not use!). And Banks' unique 5 inch bellows accommodates engine movement, which prevents component damage and prolongs service life. Designed to not cause fault or error codes.
