The aFe Magnum FORCE Stage-2 Cold Air Intake System is a direct factory replacement designed specifically for Dodge and RAM 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine from 2007 to 2012. This complete intake upgrade is engineered to enhance engine performance by increasing airflow and delivering cooler, denser air to the combustion chamber. Ideal for enthusiasts and truck owners seeking improved horsepower, torque, and throttle response, the Magnum FORCE system offers a reliable and efficient solution without requiring complex modifications or sacrificing engine protection.
By replacing the restrictive factory intake, this system unlocks your truck’s full potential, making it a perfect upgrade for daily drivers, towing enthusiasts, and performance-minded owners alike.
The Magnum FORCE Cold Air Intake System combines advanced engineering with premium materials to optimize airflow and safeguard your engine. Key features include:
The intake system features a rotomolded plastic intake tube crafted with smooth contours and gentle bends to minimize airflow turbulence and maximize efficiency. The one-piece aluminum heat shield is powder-coated for long-lasting durability and engineered to seal tightly against the hood, effectively isolating the air filter from engine heat to ensure intake of cooler air. The Pro DRY S air filter utilizes three layers of randomly porous synthetic fabric, balancing high airflow with superior filtration without the need for oiling. All sealing surfaces and structural components are made from 100% polyurethane, providing resilience under high temperatures and extended service life.
Replacing the factory intake with the Magnum FORCE Stage-2 system allows your 6.7L Cummins engine to breathe more freely, resulting in improved combustion efficiency and increased power output. This enhanced airflow delivers sharper throttle response and can contribute to better fuel economy under certain driving conditions. Additionally, the open-element design combined with the smooth intake tube produces a more aggressive engine induction sound, enhancing the driving experience without excessive noise.
This cold air intake system is designed for a direct bolt-on installation using factory mounting points, requiring no cutting, drilling, or permanent modifications. The included heat shield installs quickly and securely, and the system comes with detailed installation instructions to guide you through every step. It fits 2007 through 2012 Dodge and RAM 2500 and 3500 models equipped with the 6.7L Cummins diesel engine, ensuring a perfect fit and reliable performance.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
