Banks Ram-Air Intakes start out as CAD software prototypes, 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 42132-D cold-air intake with enclosed housing, huge inlet/outlet, and large filter improves flow up to 57%, increases power and fuel economy, and reduces exhaust gas temps (EGT). The stock design is wide-open to hot underhood engine air, and hot air robs your GMC/Chevy of power. Banks Ram-Air houses a giant lifetime filter in an enclosed cold-air box, which inhales more cool, dense outside air than stock for more power and mileage, and lower EGTs, and less sooty smoke pluming from your 6.6L Duramax. Banks 42132-D Ram-Air accommodates engine movement with bellows to prevent component damage for longer service life. Designed to not cause fault or error codes.
