2011-2012 Duramax Banks Cold Air Intake Kit (42220)

Fits

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 42220 cold-air intake with enclosed housing, huge inlet, and dome-shaped filter improves flow by up to 35%, 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 GMC/Chevy of power.
