Product Description

The K&N 57-1548 Cold Air Intake System is engineered for the 2005-2009 Jeep Grand Cherokee and 2006-2009 Jeep Commander equipped with the 4.7L V8 engine. This high-flow intake replaces the factory air path with an optimized HDPE tube and oversize filter to increase airflow and deliver measurable performance gains.

Thanks to the rotationally-molded HDPE intake tube paired with a large oiled-cotton gauze High-Flow Air Filter™, the 57-1548 system supports increased airflow while maintaining effective filtration. The reusable filter design allows for extended service intervals (up to 100,000 miles under typical highway conditions). A custom heat shield is included to minimize heat soak and keep intake air cooler and denser for improved throttle response and performance.

Installation is designed to be straightforward and uses factory mounting points with common hand tools - many owners complete installation in under an hour. With CARB Executive Order D-269-37 the system is street-legal in all 50 U.S. states (verify label on kit). Fitment is confirmed through model year 2009; coverage for 2010-2025 remains unconfirmed and should be verified before purchase.
