      Review & Installation 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.

        The Ford Performance oil seperator looks like a stock piece when installed. The fit was great and it took less than 5 minutes to install. I been wanting one for a long time and got this for Christmas. Very nice piece and I know I can trust performance from Ford Performance!

        Slick Piece, well madd

        Install couldn’t have been easier (10mins). Only thing I didn’t like was it doesn’t account for the plastic wire holder that you originally cut. I added a zip tie to hold it but this is a minor gripe. Guys, it easily drains. There’s tons of videos on this as you can disconnect the tubes or unbolt the top cap and use a plastic syringe.

        Super easy install with OEM fitment and stock look. I chose this oil-air separator over others because it actually mounts to the car. The install took approximately 5 minutes.

        There is a Drain

        Various reviews complain about no drain to this, but simply not true. It's designed to loosen the pushpin fasteners and disconnect the catch can from the hoses....very easy and pours out the bottom line. You will have to take the strut bar off if your car has one to get plastic cover out, just to make it easier to get in there.

      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 (6)

      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 (3)

      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.

      I have and RS3 will this work with the supercharger and will it still pass state testing?

      • The Ford Performance Oil-Air Separator will not work with a Roush Supercharger. Legality for your state emissions program will depend on the individual state.

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

      • 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!
