    Review & Install Video

    Hey, guys. Stephanie with americanmuscle.com, here with a review and install of the Ford Performance oil-air separator for the 2011 and newer Coyote. An air-oil separator is a simple mod that does some good for all applications. A catch can might not be one of the first mods that's on your list, or it may not even be on your list at all. But it's a very functional piece that has benefits to it, and it can do good for even a completely stock motor. The Ford Performance oil-air separator is going to be for those of you out there that are looking for an air-oil separator that has OEM hoses and fittings, and that has an OEM look instead of the aftermarket look that most separators have. The big difference with this separator is really going to be in the looks and styling. This really does look like an OEM part. I mean, look at it. It looks like something that you'd pop your hood and see in the engine bay, right from the factory. This is way more low-key than other separators and catch cans in my opinion, and it's not something that's going to stand out in the engine bay. As far as functionality, you're seeing the same benefits here and you might be wondering why you'd even want to consider an oil separator. With an internal combustion engine, the ignition of the air and fuel mixture inside of the combustion chamber is ignited and it forces the piston down. There's a small amount of that mixture that leaks past the piston rings and into the crank case. This is blow-by, and in that blow-by there's an oil mist. The blow-by and oil mist will settle in the intake, and over time they're going to form a gunky buildup. Now, technically speaking, there can also sometimes be some condensation, along with oil mist and blow-by. If you let all of this hang out, worst case, this stuff can make it into the oil inside of the crank case. This is not a good thing, and it's considered oil contamination and dilution. So you've got your PCV valve to help fight this issue. A PCV valve alone has its own list of weaknesses and engines have regulations, as far as emissions go. So the current setup, as far as crank case ventilation systems, means that an engine will have detonation or knock when oil is in the combustion chamber. Another thing that happens is carbon buildup on the piston tops and the valves, as well. Enter into the scene the oil separating catch can. It's going to push these gases, the blow-by and the oil mist, and the condensation, through a baffle system that's going to trap the oil and separate it from the other gases. The gases are going to be allowed to continue through the intake, so they can be burnt off, and the oil will stay in the catch can, so it doesn't move on and cause issues for the engine. This separator is going to sit right on the passenger side in front of the engine. It has a different, unique filter media system that's going to separate the air and the oil. It's also going to come with OEM fittings and hoses, which is a nice feature. The only thing that I don't like about this separator is the fact that there's no drain in the separator. A lot of other options out there have a drain in the bottom, which will allow you to easily drain the can. You have to find another way to empty this can, but that isn't the end of the world. Most people found that a syringe worked well for them, or you can always remove the separator from the car, since it installs easily, and drain the oil that way. When it comes to application, Ford Performance does label this as an "off-road use item only." That's because it does interfere with the PCV system and what's standard and accepted, as far as emissions and regulations requirements. When it comes to price, you're looking at just over $150 for this separator. Now, this isn't the least expensive option that you have, but it isn't the most expensive either. You are getting a direct-fit item here, with OEM hoses and fittings. The install for this is very easy, and should take about a half-hour tops. I'm going to call it a one out of three wrenches on the difficulty meter. All you're looking at needing to do is removing the breather hose and the passenger side valve cover, removing the electrical harness, and getting the separator into place using the provided pushpins. You reinstall the electrical harness and install the breather hoses as well, and that's all you're looking at for the install. Wrapping things up here with the Ford Performance oil-air separator, this is a direct-fit separator that comes with OEM hoses and fittings. The separator has an OEM appearance, and you can check it out more online right here at americanmuscle.com.

    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.

    5 Top Rated Questions

    Does this fit with the Ford Performance Power Pack 2 installed? On fords website it says it will not fit properly due to the larger throttle body, just wanted to see if you tried it.

    • No, this would have clearance issues when coupled with the larger throttle body and would require modification to work.

    Helpful (2)

    I see some manufacturers have a separator for passenger and drivers side, and some like the Ford Performance have only for passenger side. To truly get the benefit on Oil separation, don't you need to have one for each side? Thanks in advance.

    • The Ford Performance Oil-Air Separator and many others are designed for the Passenger side, as this is where the majority of oil is pulled through. Some manufacturers offer a driver side separator as well for a complete setup, however the driver side will collect less oil.

    Helpful (2)

    Once this separator is filled with oil, do you empty it or dispose the entire separator? Also, why can't this be used on public highways and the other aftermarket (JLT) separators are allowed on public roads? Thanks.

    • It alters the way the engine, which has been emissions tested, processes something the affects emissions. In this case, it removes oil which no longer burns in the engine and so, one would assume, actually makes the engine burn cleaner, not dirtier. But the way testing works, they need to get the whole thing recertified. Which is expensive. So they don't bother and then declare it's for off highway use only... knowing full well that most people will buy it for on highway use. Why do Ford call theirs out as for Off Highway Use while others don't? Because Ford have lawyers who scrutinize such things and make them while the smaller after market makers either don't have the lawyers, don't know to ask the lawyers or don't think it's a big enough issue to worry about. Being Ford's size makes you a lot more of a target.

    What sort of modification is required to make this fit with the Power Pack 2?

    • While this will have issues with the larger throttle body in terms of clearance we have been aware that this could fit with custom modifications, as to the modifications themselves we would advise to reach out to a local shop to see what the work would entail in order to install.

    Do they make one for the driver side on a 2013 GT? I would like to install both.

    • Unfortunately we do not currently offer one for the driver side. Only the passenger side at this time.

    Regarding the "offroad" disclaimer and to others asking inspection questions. What's the verdict? I want to protect my car from "dirtier" combustion overtime, but why wouldn't it pass inspection? A "your engine burns too clean" fine or something? Or more like "this piece over here, even if it makes combustion cleaner, didn't come with the engine" fine. 1 answer

      Will fit Performance Pack 2!!!

      Not as much of a review as I just installed it and have not seen actual oil collection as claimed. Here to say it fits on a performance pack mustang equiped with the performance pack 2 (gt350 intake and throttle body) kit without the engine cover (have not checked with engine cover). Install was smooth and effortless.

      Factory Oil Seperator

      This product has good build quality and quality hardware. I found it to be extremely easy to install and once in it looked as if it was there when it left Flat Rock. I withheld 1 star because I don't yet know if it will perform the task it is alleged to do. No difference in performance that I could detect. I saw lots of info saying I just had to have one and apparently Ford thought enough of that concept to offer one for sale. Wonder why it wasn't standard instead of the ridiculous "intake resonator tube"?

      perfect fit, perfect look.

      Ford performance Oil separator What A perfect fit for my Cal - Spec convertible! The connection hoses have an OEM quality look and connect perfectly, not lose at all. The push pin connections hold the separator in place with no unnecessary movement. The black color is a perfect match to the rest of engine bay. Top quality part. I wanted this to to be completely functionable for my occassional track runs, but also to look like it was an original part of the engine in the first place. This will be a breeze to empty when I do my oil changes. I couldn't be happier with this purchase. Highly recommend. Thanks A.M.
