      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.

        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.

        Nice Product

        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.

        Flexible Location

        I used this separator because I'm running a Procharger and it gave me the flexibility to be able to mount it on the driver's side. Very good quality and I like the drain valve. Highly recommend!

        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

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

      • You would really only need one of these.

      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!

      Why wouldn't this work on the 3.7 engine?

      • This is designed for the 11-14 Mustang GT models and unfortunately will not work with the V6 models.

      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.
