Quick Ship SKU #: AFE-50-70056-main AFE Momentum HD Cold Air Intake 20-24 GM 6.6L Duramax L5P

Why would you want to upgrade the factory air intake system on your 2020+ GM L5P Duramax? Well, that answer is multi-faceted. For one, airflow. Your engine thrives off of the turbo working efficiently and this can only be accomplished with adequate airflow. While the stock air box technically delivers airflow, more airflow will equate to even more power and better efficiency. This means more pulling power and greater MPG's.

Filter Options:

Large Three Layer Performance Air Filter:This 360-degree radial flow air filter features 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 and light off-road use. Its inverted top makes for more filter surface area, resulting in longer service intervals.

Large Ten Layer Performance Air Filter:Momentum’s unique filter-to-housing interface was built to feature the largest air filter possible. This 9” tall, pre-oiled 360-degree radial flow air filter features a 5-1/2” flange and our pre-oiled Pro 10R media with ten layers of progressively finer cotton gauze media for maximum performance and filtration. Its inverted top and large surface area provide much longer life between maintenance intervals, while reinforced metal provides maximum strength to prevent filter collapse. This media is best suited for off-road applications.

Filter-to-Housing Interface:
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.

Unique One-Piece Housing:
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 utilizes the factory air inlet, using no additional hardware, and features an optional auxiliary air inlet that pulls in additional air.

Dyno-Tuned Intake Tube:
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.

Premium Components:
Stainless-steel T-bolt clamps are included for strength, and a premium bellows coupling allows for ample flexibility. Momentum GT intakes are designed with fewer parts for a fast and easy installation.
