Description
Reduce Sludge. Reduce engine sludge in your 4.6 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 compliment your Mustangs engine compartment. The Moroso separator features 1/2" inlet and outlet fittings, and includes a 54" length of 1/2" rubber hose.

Application. This Moroso Air Oil Separator is specifically designed to fit the 1996 to 2004 GT and Bullitt Mustangs with the 2 valve 4.6L modular engine.

Fitment: 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

what is the purpose of the bottom outlet? I installed this on my 00 GT this morning, just wondering what that piece is for.

  • The bottom portion of this air/oil separator is actually the draining elbow and opening valve. Hope this helps!

Can I use this? I dont have an EGR on my mustang. Do I need this still? I understand that it uses the exhaust but since I don't have an EGR anymore I shouldn't need it right?

  • This air/oil separator does not involve the exhaust at all. This goes inline between the PCV valve and intake plenum. You could definitely use this air/oil separator.

Question Resolved

Which side of the engine should this be used on? Seems like most of these photos have the separator attached to the passenger PCV, does that side tend to vent more vapor? I have no intention of buying 2 of these

    Stop Burning oil

    Called in to learn more about the product. Knew I needed it after taking my intake out and seeing oil pooling at the bottom of the manifold. Moroso's oil air separator has a release valve to release oil in the catch can and avoids messes. Took about 30 minutes to plug everything in place. Car runs smooth and after removing plenum 2 weeks later no oil in the intake. Moroso makes a great product and American Muscle delivers it fast.

    Quality product with an easy install that does exactly what it says.

    I have a 2002 Mustang 4.6L 2V. I wanted to reduce the amount of blow by and gunk in the upper intake and decided that I would try the Moroso Air/Oil Separator as they had just released a bracket to fit my year and make. When I received the package it was very well put together, the quality of the air/oil separator as well as all hoses and mounting accessories is excellent. Furthermore, the install was a very simple and did not require any special tools other than a screwdriver and wrench with attachments. The install took about 45 minutes and looks extremely clean in the engine bay. As for the actual functionality of the product...as with almost everything else from this company it does what it says. After about 400-600km of driving I decided to empty it and sure enough out came a thick, foul smelling, black oil. Additionally, there is almost no gunk or oil buildup where the hose from the separator enters the intake meaning that the air/oil separator is effectively doing its job. This product will be even more useful to me once I have completed my forced induction setup.

    Great Quality, Great fit

    First off, This is a really nice product. Quality and all. It fit in the engine bay and really looks good. It took me roughly an hour to install but that was due to a couple slight issues I came across. I have an '04 GT, and I don't know if it makes much of a difference but I think it did. I had to route the tubes much differently than showed in the directions to install this into the car. Also, I believe they made a mistake with the amount of 1/2"-5/8" couplings included. There should be 2 of them included. I had to reuse the stock pcv tube as a coupling because there was no other coupling included. Another thing is that the lengths to the tubing were way too long no matter how you bent them so I had to wing the cuts to the tubes to my own lengths to fit properly. To me, these weren't major issues because now my air/oil separator looks a bit cleaner and different than other people's. Overall I still give it 5 stars, the only thing I would add is another coupling to only use the tubing included in the box rather than reuse the pcv tube. Also, Thank you American Muscle for the one day shipping. I ordered it yesterday morning and got it the next day.

    Keep it clean

    Great product! The fit and finish is very nice. Installation instructions are straight forward. I would recommend this product for all mustang owners, including all supercharged mustangs. It will help to keep oil from contaminating your intercooler and Intake manifold. It helps to reduce engine oil sludge and keeps your engine clean. I used A/N hose fittings to complete the installation. Best of all this product is made in the USA.

    Good craftsmanship

    Moroso makes it easy to add a catch can to your PVC system with this piece. Good place to mount the can and better than a vented setup to keep the engine bay cleaner.

    great product

    very high quality product, the only problem that I saw with it is that while it is sold to cover 96-04 cars, it only comes with hoses & fittings for the later cars (ie. 1/2" hose & fittings as opposed to the early cars which take 3/8" hose for their pcv system). other than that, nice part.
