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 flow bench, then dyno testing and on-vehicle testing. Banks 42210 cold-air intake with enclosed housing, huge inlet, and dome-shaped filter improves flow, 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 Ford F250/F350/F450 of power.
