      Reduce Sludge. Make the most of your time on the track by preventing performance robbing blow-by from lining your engine in sludge with the Oil-Air Separator. Specifically designed for the Coyote or Voodoo engine, this separator boasts an OE look for a clean look without compromising function. It installs in your coyote's PCV line to filter out oil vapor from your crankcase exhaust that can easily gum up your throttle and intake or end in engine sludge.

      High Quality. This Air-Oil Separator is precision molded for custom fit and durability. It features a unique filter media to separate oil vapor from your Mustang's PCV system. Highly engineered for a factory look and fit, this kit includes OEM hoses as well as fittings, providing superior quality and lasting performance.

      Easy Installation. This kit is designed as a direct fit for your 5.0L Coyote or 5.2L Voodoo engine and requires no modification to your factory equipment for use. Fully plug and play, this kit includes easy to use push pins and OE fittings for a quick and painless upgrade.

      Application. This Ford Performance Oil-Air Separator is specifically designed for use on 2011 to 2017 5.0L Mustangs and 2015-2020 GT350 Mustangs. Not intended for use on highways or public roads.

      Please Note. This Oil-Air Separator is not designed to be used on Mustangs with the Ford Performance Power Pack 2, part# M-9603-M8A, due to the Throttle Body stack up/alignment.

      Technical Note. This part has been designed and is intended for off-highway application only. Installation of this part on a vehicle that is driven on public roads may violate U.S. and Canadian laws and regulations relating to emission requirements and motor vehicle safety standards.
