The K&N Air Oil Separator for 2011–2023 Ford F-150 3.5L captures oil from crankcase blowby in a high-capacity reservoir to protect the engine and intake tract. Engineered for specific vehicle fitment, it installs using factory-style hose connections in about 30 minutes and replaces the factory line to allow convenient mounting. No tools are needed to check or empty the collector, and the unit is backed by a No-Hassle Lifetime Limited Warranty.
