Description
The aFe POWER Momentum HD Cold Air Intake System with Pro DRY S Filter is engineered to deliver exceptional airflow, increased torque, and superior filtration for 2017–2019 GM HD trucks with the 6.6L Duramax diesel engine. Designed for heavy-duty towing, off-road use, and performance enthusiasts, this system combines advanced engineering with durable materials to maximize diesel power.
Dyno-tested results show the Momentum HD intake delivers up to +15 horsepower and +37 lb-ft of torque, while outflowing the factory intake by up to 66%. The system’s CAD-designed roto-molded intake tube and high-quality one-piece sealed housing ensure smooth airflow and optimum air velocity for maximum efficiency and power.
Pro DRY S Oil-Free Air Filter
At the core of the system is a massive Pro DRY S 360-degree radial flow air filter, featuring 3 layers of progressive synthetic media for 99.2% cumulative filtration efficiency. The filter’s unique design allows for maximum airflow while simplifying maintenance. Its reinforced metal construction prevents filter collapse and ensures long-term durability.
One-Piece Sealed Housing with Sight Window
The intake features a custom CAD-designed roto-molded housing made from heat-resistant cross-linked polyethylene (XLPE). This one-piece design reduces heat soak and eliminates multiple housing components. A built-in sight window allows for quick filter inspection without disassembly, while an optional urethane plug enables auxiliary air inlet management.
Dyno-Tuned Intake Tube
The system includes a CAD-designed, dyno-tuned intake tube engineered to fit with the stock mechanical fan, achieving maximum power gains while maintaining a perfect fit.
Premium Installation Hardware
High-quality stainless-steel T-bolt clamps and reinforced couplings ensure a secure, leak-free installation. Fewer parts simplify assembly for a fast and hassle-free setup.
