Product Description

The aFe Power 51‑10242 Magnum Force Stage‑2 Cold Air Intake System is a high‑performance intake designed specifically for Jeep Grand Cherokee (WK) and Jeep Commander (XK) models equipped with the 5.7 L V8 gasoline HEMI engine from 2005 through 2010. Featuring a large 4½″ Pro DRY S dry synthetic air filter that requires no oiling, this intake dramatically increases airflow while maintaining excellent filtration efficiency and convenience. The one‑piece heat shield helps isolate the filter from hot engine air for cooler, denser intake air.

The Stage‑2 intake includes a dyno‑tested molded intake tube with smooth bends to maximize airflow velocity and throttle response. With installation that bolts directly to the factory mounting points and no cutting or drilling required, this system provides up to approximately +19 HP and +25 lb‑ft of torque gains over stock with a ~73 % increase in airflow. The washable and reusable Pro DRY S filter and durable hardware make this a long‑lasting performance upgrade that is CARB‑legal for 50‑state use (CARB EO: D‑550‑27) for supported vehicles.
