Product Description

The K&N 77-2618KC Cold Air Intake System is designed for 2021-2022 Ford E-350 and E-450 Super Duty trucks with the 7.3 L V8 engine. By replacing the factory airbox and stock ducting with a mandrel-bent aluminum intake tube and a high-flow cotton-gauze filter, this system improves airflow into the engine, enhancing boost response, throttle feel, and overall engine efficiency. The intake path draws cooler, denser air from the engine bay, supporting better combustion and potential horsepower and torque gains.

Installation is bolt-on using existing factory mounting points and requires only basic tools. The included air filter is washable and reusable, offering long service intervals and reduced maintenance costs. For owners seeking a reliable, durable, plug-and-play upgrade to improve airflow, throttle response, and engine performance, the 77-2618KC provides a proven solution with K&N's lifetime warranty.
