Protect your Ford F-150 with the K&N Air Oil Separator

The K&N Air Oil Separator helps keep blowby oil from reaching the intake, preserving airflow and helping maintain engine cleanliness over time. This unit is designed for the Ford F-150 line from 2011 through 2023, including the F-150 Raptor from 2017 to 2023, and it slots into the engine bay with factory-style hose connections for a clean, quick setup.

How it works and what it offers

Blowby oil can entrain tiny droplets that ride along the crankcase vent into the intake tract. The K&N separator provides a high-capacity reservoir to collect those droplets, reducing the chance of oil contamination in the intake manifold. While results can vary based on driving style and conditions, many drivers notice smoother operation and more consistent airflow as the unit operates in the background.
