aFe Power Magnum FORCE Stage-2 Si Cold Air Intake System Pro DRY S Select 2004-2007 Ford (V8-6.0L)

Fits select 2004-2007 Ford Excursion and F-250/F-350 Super Duty models (V8-6.0L Power Stroke Diesel).

The aFe Power Magnum FORCE Stage-2 Si cold air intake system is engineered to optimize airflow and engine protection for Ford 6.0L diesel trucks. This system features a fully sealed, heat-resistant roto-molded housing that shields the air intake from high engine bay temperatures. The CAD-designed, dyno-tuned intake tube maintains a perfect fit while maximizing air velocity, resulting in a measured +29% flow increase over the factory assembly.

At the heart of this system is the Pro DRY S air filter—a 9-inch tall, oil-free, 3-layer synthetic media filter providing 99.2% filtration efficiency. This washable and reusable filter requires no oils for cleaning, offering maximum convenience. The kit includes a versatile adapter to accommodate both Mass Air Flow (MAF) and temperature sensor configurations. Installation is a direct bolt-on process utilizing factory mounting points with no cutting or drilling required.
