Banks 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. Banks 42142-D cold-air intake with enclosed housing improves flow up to 57%, increases power and fuel economy, reduces exhaust gas temps (EGT) and sooty, black smoke. The stock filter-on-a-stick design is wide-open to hot underhood engine air, and hot air robs your GMC/Chevy of power. Banks Ram-Air is the only aftermarket intake with bellows which accommodates engine movement and prevents component damage for longer service life.
