• Dyno-proven performance gains of up to +17 horsepower and +18 lb-ft of torque
• Outflows the factory intake by 38%, with a measured airflow of 550 CFM at 7” H2O
• Open-element design showcases the air filter and produces an aggressive intake sound
• Washable and reusable Pro DRY S air filter media for easy maintenance without oiling
• Innovative filter-to-housing interface reduces hardware and simplifies installation
• Utilizes factory mounting locations for a secure, hassle-free fit
• Large three-layer synthetic media filter providing excellent filtration and dust capacity
• Heat-resistant XLPE polymer intake tube designed for durability and optimal airflow
• Multiple air inlets to draw in cool air under load for maximum performance
• Includes stainless-steel clamps and premium bellows coupling for strength and flexibility

Construction & Design

The Magnum FORCE intake features a unique one-piece housing made from cross-linked polyethylene (XLPE), a polymer known for its heat resistance and durability. This material helps minimize heat soak, ensuring cooler air reaches the engine for improved combustion. The open-element housing design not only allows for easy visual inspection of the air filter but also enhances the intake sound, delivering a more aggressive engine note.

The included Pro DRY S air filter is a 7-inch tall, 360-degree radial flow filter with a 6-1/8” x 4-1/8” oval flange. It uses oil-free synthetic media layered progressively to provide excellent filtration efficiency and dust holding capacity without the need for oiling, making it ideal for street and light off-road use.

The intake tube is computer-designed and dyno-tuned to maximize power gains while maintaining a perfect fitment. Its XLPE construction ensures resistance to heat soak and long-term durability under demanding conditions.

Performance & Sound

The aFe Magnum FORCE Cold Air Intake delivers measurable performance improvements, with dyno-tested gains of up to 17 horsepower and 18 lb-ft of torque. The system increases airflow by 38% compared to the factory intake, allowing your engine to breathe more freely and respond quicker to throttle inputs.

In addition to power gains, the open-element design produces a distinct, aggressive intake sound that enhances the driving experience without being overly loud or intrusive. This sound signature is especially noticeable under acceleration, giving your vehicle a sportier presence on the road.

Installation & Fitment

This intake system is designed for a straightforward installation using existing factory mounting points, minimizing the need for additional hardware or modifications. The patent-pending filter-to-housing interface reduces the number of parts required, making installation faster and more reliable.

Note that for Dodge Durango models equipped with the SRT hood, the air filter sits directly under the hood vent. aFe POWER recommends purchasing the 28-10303 pre-filter to protect the air filter from rain and other environmental elements. It is also advised to avoid pressure washing around the hood vent and to exercise caution when driving in heavy rain to maintain optimal performance and filter longevity.
