V3 Street Series Air/Oil Separator by IAG Performance

The IAG Performance V3 Street Series Air / Oil separator (AOS) is an excellent investment to keep your Subaru vehicle running well. The Street Series AOS maintains OEM PCV system functionality, but supplements its capacity. The Street Series AOS design is based on years of extensive testing on standard and competition applications. The Street Series AOS' large, 1-liter, cast aluminum swirl pot canister more effectively separates oil from the PCV system upstream of PCV gasses return to the intake system. The Street Series AOS' fully-heated cast aluminum housing, superior venting, and unique, patent pending, baffle design set it apart from the rest. The Street Series AOS is compatible with all fuel types, extends engine life, improves crankcase ventilation and is compatible with standard ECU calibrations.

Keeping oil out of the engine intake tract is extremely important towards preventing premature mechanical failure and maintaining performance. Oil in the intake tract of the engine has several detrimental effects. First, the oil coats the internal portions of the intake, intercooler, and piping. This oil may cause premature failure of rubber or silicone hoses, which leads to failed connections.

Once the oil reaches the intake tract it will directly enter the intake manifold and then the combustion chamber of the engine. Oil inside of the combustion chamber can cause detonation and preignition, high emissions, smoke, loss of power, decreased gas mileage, and even catastrophic engine failure leading to expensive repair bills.

The Street Series AOS maintains the OEM PCV system functionality, but supplements its capacity. The Street Series AOS PCV discharge gasses return to the turbo inlet, retaining a PCV valve to draw additional suction, improving air oil separation. The Street Series AOS protects from oil dilution and lubrication failures in ethanol fueled application because the Street Series AOS captures fuel vapors out of the oil and returns these vapors to the intake tract for combustion. The Street Series AOS protects from both oil entrainment in the intake flow and oil dilution in the engine's lubrication system far better than the OEM PCV system alone.

The most popular Subaru AOS is now even better! The IAG AOS body is completely redesigned using cast aluminum and features an integrated coolant passage for better heat retention. Additionally, the V3 AOS heating system is upgraded by relocating the coolant lines to the bottom of the body using new swivel fittings, heat sleeving and an integrated coolant bleeder. These heating system upgrades will allow for a cleaner installation and less condensation buildup in colder climates. The new compact body has the same 1-liter capacity as V2, but features a sleeker design and adds removable ORB fittings for greater versatility.

  • True 360 Degree Rotating Breather Port
  • Dual Breather Ports
  • Greater Pressure Stream Oil Separation
  • Compact Cast Aluminum Design
  • Approximate 1 Liter Holding Capacity

Please Note: The IAG AOS is not compatible with most aftermarket strut tower bars.

Great Product

10 out of 10. It helps clean up some PCV hoses as well. Great product.

Fast shipping, and quality packaging as always. Installation went as expected, and AOS works and looks good in the engine bay. Thanks to the people at MAPerformance for another smooth and easy transaction!

Great product installed with my wife. I've checked oil twice now and still sitting at full.

Pull the trigger and buy it, I kicked it around in my head since I’ve seen videos and all the steps needed to complete but it was so much easier than expected. The V3 has most of the lines cut to length already. Help the life of your car and get it.

I’m big on reliability when it comes to my WRX, so one of the first upgrades was this AOS, and I do not regret the purchase at all whatsoever. It does exactly what it’s intended to do, with that being said, I installed it myself and had 0 issues with the product itself. If your looking for your first upgrade, before doing an intake or a down pipe, I highly suggest buying one of these first (besides the Accessport, Cylinder 4 cooling mod, & KillerB Oil pickup+windage tray+pan). I’ll soon be going through MAPerformance again when it comes to my fuel upgrades.

Side note: Shipping was fast, & MAP customer service is A1. I highly suggest you go through them.
