Flowbench developed, dyno-proven cold-air intake with enclosed housing improves flow up to 57 percent. Increases power and fuel economy. Reduces exhaust gas temps and sooty, black smoke. Passes the test. Again and again. Others build and ship without testing. Not Banks. Our 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! Ram-Air houses a giant 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. And it's designed to not cause fault or error codes. 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. The optional high-flow Super-Scoop is another Banks exclusive! Key Features: Enclosed housing keeps out hot, power-robbing engine air. Inhales cooler outside air for more power & MPG. Optional Super-Scoop rams cold air for more power. Extends service life and requires fewer cleanings. Reduces exhaust gas temps (EGTs) and smoke. Outflows stock and competitors up to 57%. Giant filter maximizes high-flow filtration.
