Maximize airflow, lower Exhaust Gas Temperatures (EGTs), and simplify your maintenance routine on your 2003–2007 Dodge Ram 2500/3500 with the aFe Momentum HD Cold Air Intake System featuring Pro Dry S Filtration (51-72002). Engineered specifically for the 3rd Gen 5.9L Cummins, this intake system utilizes a revolutionary one-piece, rotomolded housing and a massive, oil-free synthetic air filter to feed your turbocharger with dense, high-velocity ambient air.

Innovative Sealed Housing and Oil-Free Pro Dry S Media

The Momentum HD series is designed with structural strength and ease of installation in mind, utilizing minimal hardware and a clever sealed housing that eliminates multiple-piece joints to keep hot engine bay air out. Inside sits a massive 9-inch tall, 360-degree radial flow air filter utilizing three layers of progressive synthetic media. Because it is completely oil-free, servicing is as simple as washing it out with mild soap and water, letting it dry, and dropping it back in—no messy oils or re-recharging required.
