can make one cheap for under 30 bucks shopping at lowes or home depot...
lots of diy threads all over for many makes of cars on these. here is one for our car but if you just google diy mustang oil separator you will find many more..
i am n/a and you would be surprised how much oil blows through. your intake is most likely coated with oil already as it doesnt take long for this to happen.
I have used both the Steeda and UPR seperators/catch can. I def like the UPR version better and they have a mounting provision to attach to the 05+ strut tower bolt.
