aFe Momentum HD Cold Air Intake with Pro DRY S Filter, Part Number 50-70056D, for 2020–2026 GM 6.6L Duramax Diesel Trucks

Momentum’s unique filter-to-housing interface was built to feature the largest air filter possible. This 9” tall 360-degree radial flow air filter features a 5-1/2" flange and our oil-free Pro DRY S media with three layers of synthetic media for maximum convenience. Its progressive layering provides great filtration efficiency and dust holding capacity, while not requiring the use of oils. This media is best suited for street use. Its inverted top makes for more filter surface area, resulting in longer service intervals, while reinforced metal provides maximum strength to prevent filter collapse. Momentum’s innovative filter-to-housing interface was built to feature the largest air filter possible. Once the system is installed, the air filter can be easily removed from the housing for maintenance by only uninstalling the intake tube. The smooth one-piece sealed housing, constructed of heat-resistant cross-linked polyethylene (XLPE), features our patented (US PAT 9440175) filter-to-housing interface. Its innovative design minimizes the total number of parts, making for an easy installation. A large, clear sight window allows for hassle-free filter inspection, without having to disassemble your system. The housing incorporates factory air scoop inlets, using no additional hardware, and features an optional auxiliary air inlet that pulls in additional air. This system features a high quality, computer-designed, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit. Its XLPE material is heat soak resistant and extremely durable. Stainless-steel T-bolt clamps and a silicone reinforced coupling are used for strength and durability. Momentum HD intakes are designed with fewer parts for a fast and easy installation. Momentum HD Cold Air Intake System w/ Pro DRY S Filter GM Diesel Trucks 20-26 V8-6.6L (td) L5P

The aFe Momentum HD housing is constructed from durable, heat-resistant cross-linked polyethylene to help resist heat soak. Factory air scoop inlets are integrated into the housing, while an optional auxiliary air inlet can supply additional airflow. A clear sight window allows quick inspection of the filter without removing the housing. The patented filter-to-housing interface reduces the number of components and allows the filter to be removed for service by uninstalling only the intake tube.

The included 9-inch-tall, 360-degree radial-flow Pro DRY S filter uses three layers of oil-free synthetic media for effective filtration and high dust-holding capacity. Its inverted top increases usable filter surface area for extended service intervals, while reinforced metal construction helps prevent filter collapse. Because the filter is washable, reusable, and does not require oil, it is well suited for street-driven trucks. Stainless-steel T-bolt clamps and a reinforced silicone coupling provide a durable, secure connection.
