Steeda's oil separator kit reduces detonation, oil burning and deposits on the valves by removing oil drawn through the PCV system before it can contaminate the intake charge. Originally designed for the '03-'04 Cobras, this kit features a clear bowl and is designed for a 3/8" and 1/2" PCV system. Mounting bracket included.

Excess crankcase pressure (sometimes known as "blow-by") is vented from the crankcase through the PCV system, where it is drawn into the intake manifold and returned by the engine. This re circulated air contains aerated oil from the crankcase which is burned by the engine. Supercharged, nitrous-boosted and high mileage engines often draw excessive amounts of oil into the engine through the PCV system. The Steeda oil separator plugs into the PCV hose between the PCV valve and the intake manifold and removes aerated oil from the re circulated air and collects it in a tube that can be drained and recycled.

Oil separator kits include the oil separator and required hardware. For 04-earlier applications connecting hose is included.

Originally designed for the 03/04 Cobra's, this kit features a clear bowl and is designed for a 3/8" and now a 1/2" PCV system. Mounting bracket included.

Fits any 3/8" and 1/2" PCV/vacuum system

I'd say this is a must have.
I have a 98 Cobra with a kenne bell 2.1 I had noticed that it was smoking when i got into it, which is rarely, but would clean itself out after a pull or 2. I installed one of these and problem solved, I was getting oil into the intake tract via pcv. This thing could have been a life saver, had i not figured it out and ran into detonation. After having it on the car within the first 10-15 miles i noticed a small puddle in the catch can. If your using forced induction, I'd say this is a must have.

Works wonders!
Works wonders! Mustangs should have come with these oil separators right from the factory. The guys at Steeda were very helpful.
