Maximize airflow, lower Exhaust Gas Temperatures (EGTs), and unlock immediate horsepower gains on your 2003–2007 Dodge Ram 2500/3500 with the aFe Magnum FORCE Stage-2 Cold Air Intake System featuring Pro 5R Oiled Filtration (54-10412). Engineered specifically for the 3rd Gen 5.9L Cummins, this high-performance system replaces your restrictive factory airbox and tubing with a precision-molded intake tube and a heavy-duty powder-coated heat shield to feed your turbocharger with dense, high-velocity ambient air.

Superior Flow Dynamics and Pro 5R Oiled Media

The aFe Stage 2 system is dyno-proven to outflow the factory intake by up to 117%, delivering verifiable gains of up to 18 horsepower and 24 lb-ft of torque. At the heart of the system is a massive 360-degree radial flow air filter utilizing five layers of progressively finer mesh cotton gauze media. Fully washable and reusable, the Pro 5R filter provides exceptional filtration efficiency and maximum airflow for heavy towing and high-performance daily driving.

Key Features & Benefits

• Massive Airflow Increase: Outflows the factory intake by up to 117% to drastically reduce turbo spool times and lower EGTs.
• Pro 5R Oiled Filtration: Five layers of progressive cotton gauze media deliver maximum airflow, high dust-holding capacity, and deep turbo sound.
• Durable Heat Shield: 16-gauge powder-coated heat shield blocks hot engine bay air and seals tightly against the underside of the hood.
• Heat-Insulating Intake Tube: Smooth, computer-designed molded tube maximizes volumetric efficiency and lowers intake air temperatures.
• Secure Hardware & Fitment: Utilizes 4-ply reinforced silicone couplings and factory mounting points for a hassle-free, secure installation.
