    Reduce Sludge. Reduce engine sludge in your 5.0 by diverting nasty "blow-by" (a combination of exhaust gases and oil) into a Moroso Air/Oil Separator a.k.a. "catch can" where the contaminated oil is separated out from the exhaust gases before being recycled back into the intake to be re-burned, thus preventing the used oil from re-enter the system to gum up your engine.

    Superior Quality Materials. The body of this Moroso Air/Oil Catch is constructed from billet aluminum for strength and has a polished finished to complement your Mustangs engine compartment. The Moroso separator features 1/2" inlet and outlet fittings, and includes a 32" length of 3/8" rubber hose.

    Application. This Moroso Air Oil Separator is specifically designed to fit the 2011 to 2013+ GT Mustangs with the 4 valve Coyote 5.0L engine.

        Would putting two of these one on each side of the engine be more beneficial or just a waste of money?

        will this separator work with the 2014 shelby gt 350 with the 624hp Whipple supercharger

        • Hello! The 2014 GT350 that you are talking about is quite rare! Unfortunately this separator will not work with your vehicle, and due to the rarity of your car I am not too sure where to point you to find one. I wish you the best of luck!

        I purchased the Moroso Seperstor for my 2013 GT I want to put one on the driver side, can I mount it to the side of the air box?

        • I would not recommend mounting the Moroso Air/Oil Separator directly to the air box, however the kit comes with a bracket to mount it on the strut tower for the driver side.

        Can you use an air/oil separator and breathers together? Would there be any extra benefits? Thx

        • The Moroso Air/Oil Separator can work with a breather on the intake as well however there really wouldn't be any benefits to it.

            Looks Good

            I would give the looks of this 5 stars but installation in my opinion although not difficult just was not good. Not sure how other catch cans come but this one you need to use parts from the original setup then you need to Teflon tape all the fittings and to me that stuff should all be done already. I just installed it so I can't say if it works good or not.

            So far so good

            Product installed as described. Looks great with the secured mount and polished finish. Like others have said a clearer copy of instructions would be great but the actual install is pretty straight forward anyway. I haven't run the car long enough yet to see what collects but I'm confident it will do what it is supposed to do.

            Was everything I read about. Very nice and fun project that took an afternoon because I painted the support brackets to match car color. Have not run them yet and will be interested to see how they work. Put one on both sides of my engine.

            Looks Great, Seems to work well.

            Looks more substantial and better mounted than some of the others that cost more. Has not been on long enough to see how much oil it catches. Very well made for the money, comes with everything you need to mount.

            fixed the blow by issue

            After I installed the o/r xpipe I noticed more smoke out of the exhaust and the smell of oil. I purchased these for both the passenger and driver side and noticed the smoke went away. I drain them every couple of days. Did a trip from Austin, Tx to Pensacola, Fl and drained them shortly after and had a few soda cap full of fluid. HIGHLY recommend

            Moroso Oil separator

            I recently purchased this Moroso separator and I am quite impressed with it. It is much higher quality than many of the other oil separators I have seen other Mustang enthusiasts using. The mounting bracket and position for it also are far superior to other brands out there. Most others just hang loosly while this one is hard mounted to the strut tower brace. As well this Moroso separator has a drain valve located on the bottom which makes it very easy to empty. All in all, a superior product. Thank you Moroso and American Muscle!!

            Despite the terrible black and white photos (mostly black!) on the instruction sheet, I was able to install this well made: chrome looks thick and bright, stainless steel bracket, hoses and fittings that were easy to connect air/oil separator with no glitches in approximately 30 minutes. I have an after market strut tower brace and I did not remove it to do this work as the instructions said. Saved time not removing the 8 bolts. I did install 4 washers under the ss bracket where it goes over the brace so not to destroy the edge of the brace. Included 2 Moroso stickers to make up for the lousy pictures!

            Moroso Air/Oil Separator

            Nice product. No O rings to wear out, no plastic fittings, product is firmly mounted, not just hanging from a piece of hose. Works as intended. Removed a surprising amount of oil, based on granny driving style and automatic transmission. Design allows for a quick and easy drain without taking anything apart. No muss, no fuss. Might get one for the diesel generator on the boat

            Excellent product

            As mentioned by other review, the quality of the can is excellent. Mounting bracket seems out of place since its plain metal while everything else is finished. The only complaint is that the directions don't mention that you won't be able to completely thread the hose fittings and drain. They only went in about a turn and a half on the hoses. I thought maybe I had some bad threading and had to look at other installs to see that they also had most of the thread showing. Other than that, the directions are amazingly detailed. Rear connection is a bit tight fitting, at least on my 2014. The guide makes it look like its a nice smooth arc but its more trial and error trimming down the length to get it to make the connection without too much stress on the valve connection or kinking the hose.

            This was very easy to install and the directions were clear. I took my time not wanting to damage the pic fittings that must be used and removed from the stock plastic hose. I added a zip tie to hold the return hose away from the oil filler cap. See my picture.

            Must have Coyote upgrade!

            I'd read quite a bit about PCV oil off the passenger side of the 5.0L engines, so I decided to give this a try. First off, it looks fantastic under the hood. Very nice compliment to the factory Track Pack strut tower brace. The install was really straight forward thanks to some of the most detailed instructions I've seen in an aftermarket part. If the photos were in color, they'd be perfect, as a couple are a little hard to see. But descriptions are terrific and they don't skip even minor detail steps that should be self-explanatory. Some minor (I do mean very minor, I give this 5 stars all day): 1. The can and the loop that holds it to the bracket are beautifully finished and really show quality. But the bracket is just a piece of steel cut and bent to shape. Takes away from it just a little bit. 2. The instructions were so detailed, the only thing that could make them better is color photos. A couple were a little hard to see, but the instructions made up for it for the most part. 3. Include the PCV connectors. I bought a second PCV hose so I could retain the stock one, and pillaged the connectors from that. For the price, the connectors should be in the package. I do need to note, when I put this on, my car only had 15 miles on it...literally drove it home from the dealer to install this. I was surpised at the amount of oil already accumulated in the stock line that you take off. Makes a catch can a crucial piece IMO.

            A Good Air/Oil Separator for the Money

            I looked at all of the different brands of air/oil separators that were offered by AM. Although a bit more costly than some of the others, the Moroso unit offered a rugged mounting bracket and the ability to drain the catch container without removal from the engine compartment. The container is nicely polished and engraved with the Moroso logo on top. The mounting bracket is not polished and I took the easy way out and painted the bracket with high-heat gloss black paint, which matches the engine compartment of my all-black 2012 GT. I have only had the separator on for a few hundreds of miles so haven't check it yet, so can't really comment on its efficiency, but like other Moroso parts I have used in the past, I am sure it works as advertised. I mounted this unit on the passenger side and plan to purchase another kit for the driver's side PVC valve to ensure I catch all of the oil mist before it enters the intake tract. I am unsure why some reviews have stated that it is necessary to purchase additional fittings or hoses. The install is clean and works perfectly without any modifications. Highly recommended.

            Room for improvement.

            The canister and mount are amazing quality. But the fittings / hoses could use some work. I like the idea of being able to drain the oil from the bottom. But the gold fitting is at a 90° angle causing oil to not fully drain from the small tube. The orange plastic piece that attaches to the 90 degree drain pipe has spot welded itself to the drain pipe making it extremely hard to remove. With the under hood temps it seems to have "shrinky dink'd" itself onto the drain pipe. The fittings are at a sharp 90 degree angle, causing the hose to want to kink. Adding the fittings to the canister is tricky. They sit at a very odd position when snug so you have to tighten / loosen the fitting to position it where you want it to sit. I recommend installing your hose onto your fitting before you attach the fitting on to the canister. I am sure my canister is not working properly. My fittings were loosened when trying to install them, causing them to be positioned at an odd angle when snug. My hose now seems to pull my fitting lose from the canister.I am not sure if i distorted the fittings or the canister itself, but the fittings are facing odd directions when they were snug. Add the hose to the mix and it will pull on the fittings causing them to come loose. I am going to try and figure out a way to install a 45° fitting that can be tightened without having to rotate the whole fitting. I also would like to replace my current hose with an oil rated nylon braided hose. I expected so much more for the price. But would not go with anything else i have seen on the market if that makes any sense.

            Nice Look

            I bought this product because I read in several forums that it would work. I love the appearance andd how easy it is to put together, will not fit where the instructions say to intall it on a 2010 Roush 427R. The inlet is in the way and I was ot about to try to drill any kind of holes on my car. So I improvised! I submitted a pix of a blue mustang with the Moroso oil separator near the brake master cylinder. It is free floating for now until I can find some kind of bracket. Lucky it sits just fine, doe not move hardly at all.
