aFe 54-80512 Magnum FORCE Stage-2 Si Cold Air Intake System with Pro 5R Filter

The aFe Magnum FORCE Stage-2 Si Cold Air Intake System (PN: 54-80512) is a fully sealed, high-performance cold air intake engineered to significantly increase horsepower, torque, and throttle response. This dyno-proven system delivers +23 horsepower and +25 lb-ft of torque while outflowing the factory intake by an impressive 69%, making it one of the most effective bolt-on performance upgrades available.

Key Features:

• Sealed Heat-Shielding Housing: Fully enclosed cross-linked polypropylene rotomolded plastic air box replaces the restrictive factory unit, with a built-in ram scoop that draws cold, dense air from outside the engine compartment for maximum combustion efficiency
• Black Powder-Coated Aluminum Cover: Attractive black aluminum cover with auxiliary inlet duct improves airflow while providing easy access to the filter for cleaning and maintenance
• Pro 5R Conical Air Filter: Massive 5-1/2" washable and reusable Pro 5R oiled cotton gauze conical filter provides 360-degree airflow and is built to last a lifetime with proper maintenance
• Heat-Insulating Molded Intake Tube: Precision-engineered molded plastic intake tube replaces the stock intake tract and maximizes airflow volume and velocity for improved volumetric efficiency
• Hassle-Free Bolt-On Installation: Utilizes all factory mounting locations — no cutting or drilling required; includes all vehicle-specific hardware and instructions
• 50-State Legal: CARB exempt under Executive Order D-550-15, legal for use in all 50 states including California

Kit includes the air filter, rotomolded housing, black aluminum cover, and heat-insulating molded intake tube. The Pro 5R filter is constructed with 100% polyurethane for long life and is washable and reusable for the life of the vehicle.
