All of these oil separators work by capturing oil vapor and particles from your 2011-2014 F150 5.0L's PCV system before they enter your intake, which means you'll get an improved overall air/fuel mixture in your truck's cylinders and less oil coating your intake, throttle body, and manifold. After you have a catch can, make sure to take a look at our brake upgrades or our tonneau covers. Ford F-150 Fitments: 2011, 2012, 2013, 2014 Ford F150 with 5.0L V8 engines.
