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.

AOS

Packaging was great and I was very happy with the color. Since it's a more advanced install than I can handle, I had a shop install it for me, but anyone with a good amount of experience working with FA20's shouldn't have trouble. The neon looks great in the engine bay with a blue WRX.

Jordan,

I run this same AOS and I couldn't be happier! IAG Performance has designed this AOS to best protect your motor from any harmful gases and contaminants which keeps you on the road longer! It can definitely be a more intensive install and should be done only if you are confident enough to do it. It looks fantastic in your engine bay! Thank you for the 5 Star Review and added pics!
