      Reduces Engine Sludge. Stop power robbing engine sludge from hampering the performance of your VooDoo powered Shelby GT350 or GT350R by installing a genuine Ford Performance Oil-Air Separator. Better known as a catch can, an Oil-Air Separator prevents oily crankcase exhaust from re-entering your Mustang's PCV system where over time it can gum up your throttle body and intake robbing you of precious power. Whether your GT350 is your weekend driver or a dedicated track car a Ford Performance Catch Can is a must to keep your Shelby running at its best.

      Ford Performance Quality. Ford Performance proudly designs and manufactures their Oil-Air Separator right here in the USA. This GT350 Oil-Air Separator is precision molded from an OEM quality plastic material for a direct fit installation. Featuring a factory appearance this Separator will look right at home in your Shelby's engine bay.

      Easy Installation. Ford Performance designed their Oil-Air Separator to be an easy straight forward install that can be completed in about 30 minutes with just basic hand tools. The included PCV silicone hoses feature pre-attached factory quick-disconnect fittings making this Separator a true plug-n-play installation. All the needed hardware and brackets are included, with no extra modifications or cutting required.

      Application. This Ford Performance Driver Side Oil-Air Separator is specifically designed for use on 2015 to 2020 GT350 and GT350R Mustangs equipped with a 5.2L VooDoo V8 engine. This Ford Performance Separator is designed for use with factory GT350 or GT350R Cold Air Intakes only.

      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.

        Just what I wanted

        Factory look installed driver and passenger separators should still be able to pass smog in a couple yrs

        Worth it

        A little strange to install as you need to cut some insulation but otherwise keeping oil out of your intake is a good idea

        Ford Performance Oil-Air Separator

        Less oil problems with this little device. I had low oil until I installed this Ford Performance Oil-Air Separator, I went with both the driver and passengers side devices.

        Oil/Air Separator

        Quality product that is easy and quick to install. What any performance car should have on each side of their V-8. Recommend buying driver’s and passenger’s side.

        Super easy install

        Install took less than 10 minutes. Fit and finish is top notch as you would expect for an OEM Ford performance part.

        Perfect addition

        The product fits perfect. Make sure you trim enough of the sound deadening material.

        Ford oil seperator

        Very good product. Not very happy with the cheap push pins . Thought ford would have a stainless stud to install. Going to modify myself . Did not find out that left side was the one I should have purchased. Drivers side is only needed if car is being tracked . So now I will have both .

        Love it!

        Peace of mind knowing no oil can make it back into the intake(I have the passenger side separator also). Great fit if you have the cold air from GT350.

      I asked the question, "Will this work with a 2017 Mustang GT w/ Power Pack 2 that includes the GT350 Air Intake?" The answer is YES! If you have (MPN# M-9603-M8A) installed it fits perfectly.

      Will this work with a 2017 Mustang GT w/ Power Pack 2 that includes the GT350 Air Intake?

      • No, this cannot be used with GT models.

      Is there an oil separator that is compatible w/an aftermarket cold air intake?

      • We do not currently carry a driver side oil separator for 15-20 GT350s that would work with an aftermarket cold air intake. Instead, we would recommend using a passenger side separator, as you would get more blow by and benefits from running it there versus on the driver side. You can see the passenger side here:

      Hi I have a 2017 GT 5.0 with a cold air intake, would this item be compatible?

      • Unfortunately this will not fit the GT models. Only the 15-19 GT350 models.

      Do you need both side or is one side preferred more than the other?

      • That is honestly completely optional. There really isn't a wrong choice when purchasing an oil separator. Basically it functions the same regardless of whether it's on the driver side or passenger side. With that being said, you would definitely benefit from having one on each side when compared to just having a driver side or passenger side oil separator. You'll see much more engine sludge reduction.
