Looking for an edge on the competition? Check out the Banks Ram Air Intake. This high-performance intake is designed to work with your LBZ Duramax engine to give you more power and better fuel economy. The enclosed housing keeps out hot, power-robbing engine air, while reducing exhaust gas temps and sooty, black smoke. And because it inhales cooler outside air, it extends service life and requires fewer cleanings. Best of all, it outperforms stock and competitors' intakes by up to 57%. So if you're looking for maximum performance, the Banks Ram Air Intake is the way to go.
