The aFe Momentum HD PRO 10R sealed cold air intake system is engineered for 2001–2004 GM diesel trucks equipped with the 6.6L Duramax V8 LB7 engine. Part 50-74001 combines a high-flow intake design with a sealed housing to help deliver increased airflow while providing protection from hot engine-bay air and common under-hood contaminants. The system is designed using precision engineering methods to provide a strong balance of performance, filtration, durability, and ease of maintenance.

At the center of the system is a 1,000 CFM, 360-degree radial-flow PRO 10R air filter featuring 10-layer progressive cotton-gauze oiled media. The washable and reusable filter uses a large 6-inch flange with an inverted top to support high-volume airflow. A unique, patent-pending housing-to-filter interface helps optimize the internal air path, while the auxiliary air scoop can be configured with the included urethane plug according to the vehicle application and installation requirements.

The one-piece sealed housing includes a built-in clear sight window for convenient filter inspection without removing the intake assembly. Reinforced silicone couplers and stainless steel T-bolt clamps provide secure connections and long-term durability under demanding driving conditions. The aFe Momentum HD intake is EPA compliant and carries CARB Executive Order D-550-18, making it suitable for applicable emissions-regulated applications. It fits select 2001–2004 Chevrolet Silverado 2500 HD trucks with the 6.6L Duramax LB7 engine; verify exact vehicle configuration before ordering.
