Product Description

The K&N 57-1542 Cold Air Intake System is engineered for high-performance V8 HEMI-equipped Dodge and Chrysler models from 2005 to 2019. Designed for the 5.7 L and 6.1 L HEMI V8 engines, this intake replaces the factory air intake path with a high-flow, low-restriction design that delivers measurable gains in horsepower and torque. With published gains of around 21 HP and over 31 lb-ft of torque, this system is ideal for performance-minded drivers upgrading their Charger, Challenger, Magnum or 300C.

Built with a premium HDPE intake tube (or Gen II variant depending on production year) and paired with an oversized, oiled-cotton gauze High-Flow Air Filter™, this system ensures strong airflow and filtration. The reusable filter means you can go long service intervals - typically up to 100,000 miles under normal highway conditions - before cleaning. A custom heat shield isolates the filter from hot engine-bay air, helping cooler, denser air reach the throttle body for improved response.

Installation is straightforward and designed for ease: using factory mounting locations and hand tools, many owners complete the job in under an hour. For states with emissions testing, the included CARB certification (E.O. D-269-76) ensures street legality in all 50 U.S. states (verify label presence). Fitment is confirmed through 2019; coverage for 2020-2025 remains unconfirmed at time of listing - buyers with later models should verify compatibility prior to purchase.
