Engineered specifically for 3rd Generation (2007.5–2009) Dodge Ram 2500 and 3500 trucks powered by the 6.7L 24-Valve Cummins turbo diesel, the aFe Power Momentum HD Cold Air Intake System (51-72003) delivers high-volume airflow without compromising engine protection. The factory intake assembly features restrictive sound baffles, sharp internal radiuses, and an airbox prone to drawing hot under-hood air; Momentum HD replaces this setup with an aerodynamically contoured, one-piece cross-linked polyethylene induction system that routes cold, dense air directly into the Holset variable-geometry turbocharger (VGT).

The kit is anchored by an oversized 1,000 CFM 360-degree radial flow air filter utilizing 3-layer progressive oil-free synthetic Pro DRY S media wrapped in reinforced metal to prevent pleat collapse under high boost. S&B and aFe both prioritize ease of maintenance, and this system features a patent-pending filter-to-housing interface that locks into a one-piece sealed airbox equipped with a clear sight window for instant visual inspection. Complete with a dyno-tuned intake tube, silicone hump coupler, and premium stainless steel T-bolt clamps, the Momentum HD system maximizes airflow velocity and throttle response.

Key Features & Benefits

• Massive 1,000 CFM Airflow Delivery: Outflows factory intake plumbing to improve turbo spool, sharpen throttle response, and lower exhaust gas temperatures (EGTs) under heavy towing conditions.
• Pro DRY S 3-Layer Synthetic Media: Progressive oil-free synthetic filtration traps fine particulate and soot without oiling, eliminating MAF/IAT sensor contamination and simplifying wash-and-reuse cycles.
• Filter-to-Housing Interface: Patent-pending mechanical interface seals the filter base directly to the one-piece housing with fewer parts, eliminating loose clamps and air bypass.
• One-Piece Thermal Enclosure with Sight Window: Fully enclosed roto-molded XLPE airbox isolates intake air from engine bay radiant heat, featuring an auxiliary air scoop and a clear inspection window for tool-free filter checks.
• Reinforced Metal Filter Mesh: Heavy-duty external wire mesh reinforces the conical filter structure, preventing media distortion and collapse under heavy manifold vacuum.
• Heavy-Duty Clamping Hardware: Includes premium stainless steel T-bolt clamps and a 2-ply reinforced silicone hump coupler designed to flex with engine torque while preventing boost leaks.
• Fast Bolt-On Fitment: Mounts directly to factory chassis grommets in under 30 minutes with no cutting, drilling, or permanent modifications.
