Banks 42132 Ram Air Cold Air Intake

The Banks Ram Air Cold Air Intake is the perfect way to get more power and better mileage out of your 2001-2004 LB7 Duramax. Extensively tested and validated, this intake system encloses the housing to keep out hot engine air, and instead inhales cooler outside air for a major boost in power and efficiency. Additionally, the giant filter maximizes high-flow filtration, helping your engine run cooler and extending its service life. You'll also see reduced exhaust gas temps and smoke. Best of all, this cold air intake outperforms the stock unit and competitors by up to 57%. For even more power gains, check out the optional Super-Scoop that rams cold air right into your engine bay.
