Key Features

The aFe Magnum FORCE Stage-2 Cold Air Intake System combines advanced engineering with durable materials to provide a high-performance upgrade. Key features include:

• One-piece 16-gauge powder-coated heat shield that requires no cutting or drilling for installation
• Choice of stylish powder-coated steel or brushed aluminum cover that blocks engine heat and directs cold air to the filter
• Precision-molded plastic intake tube designed to maximize airflow volume and velocity for optimal power gains
• High-flow Pro 5R filter featuring 360-degree airflow for superior filtration and performance
• Washable and reusable filter media with a limited lifetime warranty for long-term use
• Engineered to reduce intake noise while enhancing throttle response
• Durable construction built to withstand harsh under-hood conditions

Construction & Design

The intake system features a robust 16-gauge steel heat shield finished with a powder-coated surface to resist corrosion and heat damage. This shield not only protects the intake from engine heat but also channels fresh, cool air directly to the filter. The intake tube is crafted from molded plastic designed for smooth airflow and minimal turbulence, ensuring that the engine receives a steady supply of cold air. The Pro 5R filter uses multiple layers of oiled cotton gauze media, providing excellent filtration efficiency while maintaining high airflow rates. Its washable and reusable design reduces maintenance costs and environmental impact over time.

Performance & Sound

The Stage-2 Cold Air Intake System improves engine breathing by increasing airflow volume and velocity, which can lead to noticeable power gains and enhanced throttle response. The intake’s design also helps reduce intake noise, delivering a quieter yet more aggressive sound profile that complements the Cummins diesel engine’s character without excessive drone.

Installation & Fitment

Installation is straightforward and requires no cutting, drilling, or permanent modifications to the vehicle. The one-piece heat shield and intake tube are designed to fit precisely within the engine bay of 2003–2009 Dodge Ram 2500 and 3500 trucks with 5.9L or 6.7L Cummins engines. This ensures a secure fit and reliable performance while maintaining factory-style installation simplicity.
