Product Description

The aFe Momentum HD Cold Air Intake System with Pro DRY S filter (Part #50-70056D) is a high-flow, direct-fit performance upgrade engineered for **2020-2025 Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD** trucks equipped with the 6.6L Duramax L5P turbo diesel engine. Designed around a large dry synthetic Pro DRY S air filter, this intake system delivers significantly increased airflow and excellent filtration efficiency while eliminating the need for filter oiling - ideal for street and work truck applications. The innovative filter-to-housing interface maximizes usable filter surface area, while the heat-resistant sealed housing and clear sight window simplify routine maintenance.

Featuring a dyno-tuned intake tube and premium stainless-steel hardware, this intake provides smooth airflow, improved throttle response, and potential performance gains of up to ~+16 HP and ~+42 lb-ft torque over the restrictive stock intake. Installation is straightforward with a direct bolt-on design using existing factory mounting points - no cutting or drilling required. Note that this intake is **not CARB exempt or compliant**, making it unsuitable for use in California and other CARB-regulated states. Whether you're hauling heavy loads or cruising on the highway, the Momentum HD intake offers a measurable improvement in airflow, performance potential, and serviceability over the OEM intake system.
