Product Description

The K&N 57-1543 Cold Air Intake System is engineered specifically for 2005-2010 Chrysler 300, Dodge Magnum, Dodge Charger and Dodge Challenger models equipped with the 3.5 L V6 engine. By replacing the factory air intake assembly with this high-flow system, your engine can breathe more freely, leading to measurable increases in horsepower and torque.

Built with a high-density polyethylene intake tube and complemented by an oversized oiled-cotton gauze High-Flow Air Filter™, the 57-1543 improves both airflow and filtration efficiency. The washable and reusable filter means you can go up to 100,000 miles between services (under normal highway driving conditions). The included custom heat shield helps reduce heat soak by isolating intake air from warm engine-bay air, delivering cooler, denser air for stronger performance.

Installation is straightforward, using factory mounting points and basic hand tools - many owners complete the job in under 60 minutes. With CARB certification (E.O. D-269-37), this intake is street-legal in all 50 U.S. states. Fitment is verified through model year 2010; coverage for 2011-2025 is currently unconfirmed and should be verified for those model years.
