Brief Description: The aFe Momentum HD Pro DRY S Cold Air Intake System is designed for 2017–2019 Chevrolet Silverado and GMC Sierra heavy-duty trucks equipped with the 6.6L V8 L5P diesel engine. This system combines a sealed, one-piece airbox with a CAD-designed intake tube and a large oil-free performance air filter to improve airflow while helping protect the intake charge from engine-bay heat.

The roto-molded black cross-linked polyethylene housing is engineered for heat resistance and includes a clear sight window for convenient filter inspection without removing the airbox. Its auxiliary air inlet can remain open for additional airflow or be sealed with the included urethane plug. The intake tube is dyno-tuned and shaped to maintain clearance around the factory mechanical fan while providing a precise fit.

The included Pro DRY S filter uses three progressively finer layers of synthetic media and delivers 99.2% cumulative filtration efficiency. Reinforced metal construction helps prevent filter collapse, while the unique filter-to-housing interface maximizes filter surface area and simplifies servicing. Premium clamps and a reduced-part design support a secure, straightforward installation without cutting or drilling factory components.
