Engineered specifically for 2010 through 2012 Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins turbo diesel engine, the aFe Momentum HD Pro DRY S Cold Air Intake System (51-72004) provides elite airflow protection by enclosing the air filter in a fully sealed, rotomolded XLPE polymer housing. Factory intake boxes often restrict airflow and allow engine bay heat soak, whereas this advanced sealed system draws cooler, denser ambient air directly from the front of the vehicle using an integrated auxiliary air scoop.

At the core of this system is a massive, 9-inch tall round-oval Pro DRY S washable and reusable air filter featuring three layers of progressively finer synthetic media. Because it requires zero filter oil, maintenance is quick and clean—simply wash with soap and water, dry, and reinstall. Designed with a unique top-mount flange and revolutionary housing-to-filter interface, this kit installs easily using factory mounting locations without requiring custom ECU tuning or cutting.
