    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.

    Ask a Question

    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.

    speedy

    • 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.

    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.

    BenE

    • 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.

    It appears this catch can will not work if you have a blower on it. Can you recommend one that will fit? I have a 15GT with a Whipple on it. The benefits of a catch can are great. Too bad all Mfgs. don't include one as standard equipment

    RichM

    • At this time, we are unaware of any products like the Ford Performance Oil-Air Separator that will work with your Whipple Supercharger, other than universal kits, though this will not have the same easy connections as those that are designed specifically for your application. An example of this would be the Prosport Dual Baffle Aluminium Oil Catch Can linked below: https://www.americanmuscle.com/prosport-dual-baffle-aluminium-oil-catch-can-black-7917.html

    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!

      Not model year specific...

      purchased separator. wanted Ford specific but realized after install, this part covers to many different years. as can be seen in customer photos, the expansion tank hose in 2016/17 was relocated. this hose not only covers one of the separator screws but pushes down a bit on the corner. if you plan on removing the top to drain the oil, you have to force the hose out of the way earlier years, the hose is not an issue. not really a deal breaker but...? another interesting point is mine, did not have the hole for clipping the wiring harness back in place. what's laughable is the instructions show the hole and tell you to remount the harness! oh Ford...quality control? decided to keep the part because i'm sure it will work, but the usual does anybody check what they sell...no, seems to be an issue with many manufacturers today. it does look good...

      Looks factory and is a solid product.

      Had this for me ordered as a gift after i reseached for over a month on which one to pick up. The install was absurdly easy. I want to say first if your car is equiped with the stock performance pack strut tower brace or ford performances brace your do NOT have to removed it to remove the engine cover. I removed it and slide it under with zero issues. The oil seporator went right into place zero issues and the oem quick connects made it even easier. All said and done this took me 10 minutes or less and looks as if it was n oem part under the hood. Highly recommend this product. Fit finish is solid!

      Mounts to the block

      One thing a feel a lot of people overlook is the stress other cath cans can place on the PCV fitting. This one mounts to the block (mounts to wiring harness looms), flexes under load with the motor, and has Ford factory fittings. Every direct injection or forced injection owner should be running a catch can. This can in particular is both functional and Draining the can is annoying, yes. But a BBQ syringe fixes that hastle easily.

      Snug Fit

      My 13 year old son and I installed this in 30 minutes. The reason it took this long was because I had my son doing all the work. It’s a tight fit and it’s snug up against my GT350 throttle body motor. The clip for the variable valve timing sensors wiring harness was hard to pull out, so it was a good thing that I have a panel removal tool. Other than that, it was a en easy install and totally looks factory.

      Ford Oil Separators

      Both the driver and passenger side oil separators require a little fitment. I pre-drilled a hole for the wiring harness in the passenger side before installing and had to use another plastic rivet other than provided, along with slightly grinding down the underside of the long plastic mounting tab of the drivers side separator before installation was complete. Instructions from Ford could have been more complete. Otherwise, look good and should function fine.

      Unbelievable money well spent!!!

      This is officially the third product I’ve reviewed in my life. This product performs THAT well. Straight to the nitty gritty....I installed this piece with 8000 miles on my car and I emptied it at 13,500 miles. I extracted 70mL of oil out of the reservoir!!! There’s was still some left but I wasn’t going to go crazy trying to get all of it. That’s SEVENTY mL of oil this piece kept out of my engine in just 5500 miles!!!! Amazing! -note- I drive highly aggressive 60 of the time. Now do for the bullet points: PROS - installs in approx 30-60min (no experience just common sense) -looks just like factory piece -performs better than I could imagine CONS - is fairly difficult to empty as there is no cover to open and use a syringe to extract. Almost easiest to uninstall and pour out I am only upset my car ran for 8000 miles without this piece installed. But this while shopping for your new car and install right away. No brainer if you want to keep your mustangs power consistent through the years.
