Magnum FORCE Stage-2 Cold Air Intake System w/ Pro DRY S Filter – High-Flow Performance Intake
Unleash aggressive sound and improved performance from your Duramax-powered truck with the Magnum FORCE Stage-2 Cold Air Intake System. Designed with an oversized open-element layout, this intake not only enhances engine bay appearance but also delivers a distinct turbo whistle and aggressive intake sound under throttle.
Engineered and dyno-tested by aFe POWER, the Stage-2 system delivers measurable performance gains, increased airflow, and long-term reliability—making it an ideal upgrade for drivers seeking improved throttle response and sound without sacrificing ease of maintenance.
Dyno-Proven Performance Gains
-
Up to +4 horsepower and +11 lb-ft of torque
-
72% greater airflow than the factory intake
-
Measured flow rate: 715 CFM @ 7" H₂O
The optimized airflow path reduces restriction, helping the engine breathe more efficiently for improved acceleration and overall drivability.
Large 3-Layer Pro DRY S Performance Air Filter
This system features a massive 9-inch tall, 360-degree radial flow air filter with a 5-inch flange, utilizing aFe’s oil-free Pro DRY S synthetic media. The three-layer progressive design delivers excellent filtration efficiency and dust-holding capacity without requiring oil, making maintenance quick and clean.
The inverted top design increases usable filter surface area, extending service intervals and ensuring consistent airflow over time. This media is ideal for street and light off-road use.
Open-Element One-Piece Housing
The oversized filter is enclosed within an open-element XLPE (cross-linked polyethylene) housing, designed to reduce heat soak while showcasing the filter. This open design maximizes airflow and produces an aggressive intake and turbo sound under load.
The system reuses the vehicle’s factory air inlet, requiring no additional hardware while maintaining efficient airflow routing.
Dyno-Tuned Intake Tube
A computer-designed, dyno-tuned intake tube ensures maximum power gains while maintaining precise fitment. Constructed from heat-resistant XLPE material, the tube resists heat soak and provides long-term durability under demanding conditions.
Fast, Hassle-Free Installation
The Magnum FORCE Stage-2 intake is a direct-fit system that utilizes factory mounting locations. No cutting or modifications are required, and all necessary clamps and hardware are included. Thanks to the patent-pending filter-to-housing interface, this system uses significantly fewer components than traditional intake designs, allowing for easy filter removal and simplified maintenance. Typical installation time is approximately 15 minutes.
