Fits select 2017-2019 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD models (V8-6.6L).

Optimize your heavy-duty truck's airflow with the aFe Power Momentum HD Cold Air Intake system. Engineered for the 6.6L diesel engine, this system features a unique one-piece housing made from heat-resistant, black cross-linked polyethylene (XLPE). The roto-molded design eliminates multiple components for a simplified installation while a clear sight window allows for quick filter inspections without opening the air box.

The system includes a CAD-designed, dyno-tuned intake tube that maintains clearance for the stock mechanical fan while maximizing air velocity. The massive 360-degree radial flow Pro DRY S air filter features three layers of progressive synthetic media, providing 99.2% cumulative efficiency without the need for filter oil. For added durability under high-boost conditions, the filter is reinforced with a metal cage to prevent collapse.
