Banks Ram-Air Intakes start out as CAD software prototypes and are put through flow simulations and the design is refined until the simulation shows optimal performance. Then a hardware prototype is made and the design is validated on a flowbench, then dyno testing and on-vehicle testing. Banks 42279 cold-air intake with enclosed housing, huge inlet, and dome-shaped filter improves flow up to 51%, increases power and fuel economy, reduces exhaust gas temps (EGT) and sooty, black smoke. The stock design is wide-open to hot underhood engine air, and hot air robs your Dodge Ram of power. Banks Ram-Air houses a giant lifetime filter in an enclosed cold-air box, which inhales up to 51% more cool, dense outside air than stock for more power and mileage, lower EGTs and less smoke pluming from your 6.7L Cummins. Designed to not cause fault or error codes.
