aFe Power Momentum HD Cold Air Intake System w/ Pro 10R Filter for 2020-2026 Chevrolet/GMC 2500/3500 (V8-6.6L)

Fits 2020-2026 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD (V8-6.6L).

Maximize the performance of your L5P Duramax with the aFe Power Momentum HD Cold Air Intake System. This system is engineered around a smooth, one-piece sealed housing made from heat-resistant cross-linked polyethylene (XLPE) to ensure your engine breathes cool, dense air. Featuring a patented filter-to-housing interface (US PAT 9440175), this design minimizes the number of components for a simplified installation and maximum internal volume. The housing integrates directly with factory air scoops and includes an auxiliary air inlet for increased airflow, while a large, clear sight window allows for quick filter inspections without disassembling the unit.

Performance is driven by the 9-inch tall Pro 10R radial flow filter, featuring ten layers of progressively finer cotton gauze media. This pre-oiled, washable filter is reinforced with metal to prevent collapse and is specifically designed for high-dust off-road applications and maximum longevity. The kit includes a computer-designed, dyno-tuned intake tube for optimized air velocity and is secured with heavy-duty stainless-steel T-bolt clamps and a silicone-reinforced coupling.
