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

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

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.

Catbus

  • Also, mine did not come withit, and yet the ford performamce instructions specifically show it on there. Seems to be a ford performance issue...

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.

    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.

    Looks like it came from the factory, although, it didn't come with the hole drilled in it for the wire harness. The instructions are incorrect as well.

    Kept throwing codes

    I installed this very quickly. However, the instructions weren't the best. It said to reattach the wiring harness and there is nowhere to reattach it! It looks good, BUT, every 3-4 days, my check engine light would come on. I didn't pull the code, but reran my Bama tune as it always clears all codes. Too bad, it looked great!

    Oil Separator Review

    There is no pre drilled hole to reattach the electrical harness. You have to file down the ridge flat, then drill your own hole. Best way to empty is to disconnect the hose tube from the lower bowl and use a syringe with a plastic tube to draw the oil out.

    Looks factory, works really well.

    I love the way this attaches and how it looks factory installed. Only minor drawback is that the only way to empty is to open the top and use a syringe, or similar, to suck the oil out. I just emptied for the first time after installing and there was about 10ml of oil or so in there after about 3,500 miles. Not that much but enough to see how that can gunk your intake up over time.

    Oil separator review- passenger side

    Great separator, works well on the GT350 shelby's and the S550 mustangs V8's also... Fits really well into the engine bay, and looks like a factory item. You will find plenty of oil in it after 3000 miles ( I empty it at every oil change) . Highly Recommended!

    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.

    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!

    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.
