Engineered specifically for 2003 through 2007 Ford F-250, F-350, F-450, F-550 Super Duty and Excursion trucks equipped with the 6.0L Powerstroke diesel engine, the aFe Magnum FORCE Stage-2 Cold Air Intake System (51-30392) replaces restrictive factory airboxes to optimize turbo response and engine volumetric efficiency. Factory intake tracts often choke high-output diesel applications, limiting airflow under heavy towing loads.

This Stage-2 system pairs a durable 16-gauge powder-coated heat shield housing with a heat-insulating molded plastic intake tube designed to optimize airflow velocity. Filtration duties are handled by a massive, washable and reusable oil-free Pro DRY S conical filter featuring three layers of synthetic media, providing exceptional filtration without the hassle of filter oils.

Key Features & Benefits

• Oil-Free Pro DRY S Air Filter: Features a 3-layer progressive synthetic media construction that is 100% washable and reusable without requiring messy filter oils.
• Superior Airflow Dynamics: Outflows the restrictive factory stock intake system by up to 31%, reducing turbo lag and improving throttle feel.
• Dyno-Proven Performance: Generates verified maximum gains of up to +9 horsepower and +39 lb-ft of torque on stock calibrations.
• Heat-Insulating Plastic Tube: Molded cross-linked polymer intake tract resists under-hood heat soak better than metal pipe alternatives.
• Durable Powder-Coated Shield: Encloses the filter in a sturdy 16-gauge steel heat shield designed to seal against engine bay heat.
