Product Description

The Banks 42175 Ram-Air Intake System is engineered for the 2007.5-2009 Dodge Ram 2500/3500 6.7L Cummins, outflowing the restrictive factory intake by up to 50% while delivering up to 28 horsepower and 52 lb-ft of torque. A giant dome-shaped filter and huge inlet maximize filtration area for fewer cleanings, while the enclosed housing keeps hot, power-robbing engine bay air out and directs cooler, denser outside air straight to the turbo.

Banks Ram-Air is the only aftermarket intake system with an exclusive 4-1/2" bellows to accommodate engine movement, protecting components and extending service life compared to systems without this flexibility. Every Ram-Air system starts as a CAD software prototype, runs through flow simulations, gets tested on a flowbench and on the actual vehicle, and is finally density-tested against stock and competing intakes to confirm real-world performance.

The included lifetime cotton gauze filter, pre-oiled for maximum filtration efficiency, traps dirt and debris while delivering greater air density to the turbo inlet than every competitor Banks has tested. This system is designed to never trigger fault codes or error lights, and pairs with the optional Super-Scoop (Banks 42190) for even more cold, ram-fed air. Built for 6.7L Cummins owners who want proven, genuine gains in power, fuel economy, and reduced EGTs.
