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 Mustangs equipped with a 5.0L or 5.2L engine. Not intended for use on highways or public roads.

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.

How often do you have to change the filter part of this separator?

DavidM

  • Maintenance on the Ford Performance Oil-Air Separator is based on the type of driving the vehicle is subjected to, track type driving will require more frequent checks for an accumulation of oil in the separator but it is recommended to empty it every oil change with normal highway driving. The filter doesn't need to be changed just emptied. Simply remove separator and tilt so to empty oil out from the lower fitting. Do not empty from upper fitting!

Is the Ford Performance 5.0L Coyote Engine Oil-Air Separator (11-17 5.0L) compatible with Right Hand Drive (Euro and Australian) Mustangs or is a different kit required for these models? Thanks

TonyT

  • We can not confirm the fitment of the Ford Performance Oil-Air Separator on the EU models, we do not see an issue,however would recommend contacting Ford to make sure.

I jut relieved a JLT oil separator for my 17 Mustang GT not realizing it's not CARB legal. Is the ford performance oil separator CARB legal? I live in California. I'm just now finding this out.

17GT

  • This should not have issues with CARB regulations as Ford Performance has manufactured this with OEM specs in mind. For further information, please contact Ford Performance for CARB regulations.

Is this unit supposed to have the hole for the wiring harness? Most of the customer photos seem to not have it.

How often does this one require servicing, and what is it capacity?

JB

  • Its required servicing should be no different than what your stock unit required. As far as its capacity, this product will hold 9-10 oz. of oil.

Does this separator affect a performance tune? Is there a chance it will set off the check engine light if you install this while using say a 93 octane tune?

TheSarge

  • The Ford Performance 5.0L Coyote Engine Oil-Air Separator (11-17 5.0L) will not affect the tuner at all. This should not cause any check engine lights to turn on when this is installed.

    Should have came from the factory...

    This is a really nice product that should have came on the car from the factory. As most people know, you can expect anywhere between 3 and 5 ounces of oil on the passenger side after a day at the track. I am sure that Ford knew this, but decided to leave it off of the engine anyway. The fit was pretty good, except all of the pictures and video I watched installing this had the tube going from the intake to the separator backwards. I say this because if I installed the tube in that orientation, the hose would kink up. Maybe the design has changed slightly? Anyways, still looks factory once installed. Great piece!

    Great Product

    Like other reviews have mentioned, this seperator will require a oil extracting device since there's no removable reservoir you can just dump. You'll also have to remove one of the clips that a wire is attached to for the seperator to mount properly. Very easy though. I used needle nose pliers and just pulled it out.

    I bought this oil separator to replace my JLT one. This one mounts to the engine so it does not bounce around and rub anything. It looks like it was added from the factory and is great quality.

    Looks OE, doesn't work too good

    This parts blends in under the hood, no one would think it didn't belong there. Problem is that it still lets oil through which, is exactly what it is supposed to prevent. It does catch oil and, although i have yet to try other catch cans, i believe there are better preforming products out there. If this was a factory part of the mustang i could understand but unless you care more about looking OE under the hood, try a different product.

    Perfect Ford Performance OEM part!

    This product is truly a must have, coming from A Certified Ford Senior master tech, The fact that Ford came out with this for the 5.0 tells me that they know this motor produces alot of oil through the PCV system and is sent directly to the intake manifold and through the intake ports and sticks to the valves and ports. Will also burn in the combustion chamber! Can't go wrong with Ford OEM parts. Fits perfect and looks sick!! Installed in less than 2 min to my Boss 302 intake!!

    ford performance oil separator 2017 mustang gt

    I did a lot of research on oil separators and decided on the ford performance oil separator because of its appearance and looks like it was fitted from the factory, install was very straight forward, just require a 4 mm allen key driver and syringe to empty from time to time.. delivery to Perth Western Australia was less than 2 weeks.

    Great security!

    The Ford Performance Oil-Air Separator is a great security for my new car. It looks very factory and fit perfectly. I gave it only a 4 out of 5 because there is no drain and because the hole for the wiring harness isn't there anymore.

    Ford performance quality part

    I have both the passenger side and drivers side Oil-Air separator on my GT350. They fit perfectly and are well designed. Not a performance gain you will feel but it does keep the oil from going back through the intake.

    Missing Wiring Harness Hole

    The pictures and directions show a third hole (so to speak) in the middle of the bracket to re-mount the valve cover wiring harness. However, there is no third hole on the actual product. I just used the lower hole, or you could drill a third hole if necessary. Other than that, easy install, and it's nice to have a Ford product so you don't run into any warranty issues.

    Ford Oil-Air Separator Perfect Fit

    I would challenge anyone to find a oil-air separator ("catch-can") that has more of a factory appearance, fit and finish than this part. The hoses are factory style hoses. The can affixes to pre-existing holes, the fasteners are the same ones Ford uses around the engine-bay. The build quality is as good as anything else under the hood. Emptying should be fairly easy, pop off the hoses, the push pins, open the canister and empty. Simple, effective, easily 5 stars.
