K&N KNX-2460 Engine Air Filter — 24,000-Mile Extended Life for Chrysler 300, Challenger, Charger

Premium extended-life air filtration for your Chrysler and Dodge muscle and sedan lineup

Since 1969, K&N has been a leader in performance air filtration. The KNX-2460 Engine Air Filter offers a premium, long-life solution designed to operate for up to 24,000 miles under typical highway driving. That’s about twice the life of traditional disposable filters, delivering extended protection and fewer filter changes while you focus on the road ahead.

The filter uses specially treated media—either premium synthetic or cellulose blend depending on application—to help filter intake air with high efficiency. In tests and real-world driving, this design can provide up to 99.5% engine protection by removing dust and particulates before they reach the engine. It’s built to meet or exceed OEM specifications and is engineered for quick, tool-free installation in your factory air box in minutes.

Why drivers choose KNX-2460

With premium construction and engineering that prioritizes longevity, this filter aims to provide a reliable filtration solution you can trust over the long haul. It’s a practical choice for drivers who value fewer filter changes, consistent air intake, and a fit that aligns with factory specifications.

Design and materials matter. Depending on your application, K&N uses a specially-treated premium media—synthetic or cellulose blend—that balances filtration efficiency with airflow. The rugged frame is designed to handle vibration and temperature changes while maintaining a tight seal against the factory air box.

Performance notes: While results vary, drivers often report a more direct intake feel and a steadier idle as air moves more freely through the filter. These observations reflect an emphasis on airflow management and filter integrity rather than guaranteed outcomes.

Installation and care: You can upgrade with minimal effort, and routine replacement at about 24,000 miles fits typical long-distance driving patterns. The filter is designed for easy maintenance within your vehicle’s service schedule.
