Product Description

Moroso’s newest product to keep oil out of your intake is the 1996-2004 Mustang 4.6L Oil Separator. During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors, can coat your blower rotors, intercooler fins and even dilute your gas, lowering its octane level. This happens on all engines and is even worse when supercharged as crankcase pressures are increased.

To combat this, Moroso has developed an oil separator to protect your engine. Milled from solid billet aluminum this is a rock solid piece. It has a shut off valve at the base for easy draining of the spent oil and an O ring seal to prevent any leaks. This element collects the last bit of oil droplets and drains back into the tank when the engine is shut down.

5 Stars   Awesome Piece
By on 7/7/2014
Image uploaded by Mike S. This oil / air separator is awesome. The machining of the tank body itself is very well done and the brass pipe fittings really tie it together. The kit is very complete and really blends into your engine bay quite nicely. Being able to drain the catch can by simply turning the lever on the ball valve is great compared to having to unscrew the bottom portion of the can like in other kits. Overall I'm very satisfied with this product and I feel good knowing that it is preventing oil from being recirculated into my intake and creating sludge in my engine!

Yes, I would recommend this item to a friend!
