Engineered specifically for 2003 through 2007 Ford F-250, F-350, F-450, F-550 Super Duty and Excursion trucks equipped with the 6.0L Powerstroke diesel engine, the aFe Momentum HD Pro DRY S Cold Air Intake System (51-73003) 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 using an integrated auxiliary air scoop.

At the core of this system is a massive, washable and reusable Pro DRY S 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.
