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.

Fantastic upgrade to keep your engine safe

IAG air oil separator is a must for any FA20DIT motor. Keep oil out of your ventilation system to protect your engine and prevent engine damage. Moderate ease of install. All parts and hardware fit perfectly.

Needs Instructions

Love how quickly Subimods shipped the order. Excellent item made of high quality materials. IAG includes more parts than are required for the install, which is always fantastic.

The only thing I would recommend is including instructions for the install. The video on IAG’s website helped tremendously.

10/10 would purchase again.

Mike,

We appreciate your 5 Star Review of the IAG Performance V3 Street Series AOS! This kit is one of the best on the market along with being one of the most important for your WRX! For future IAG has phenomenal pdf instructions on their website https://www.iagperformance.com/content/instructions/IAG/IAG-ENG-7182/SS-AOS-15-16-WRX.pdf
These are for the 15-16 but they also have them for the 17-20 WRX as well. I totally understand how frustrating it is not having directions to follow with something such as this to install! However you absolutely will not be disappointed with the performance of this AOS!

Love it!

It was a bit of learning to get to work on it but it was mostly making sure you put everything back together correctly that you need to take off, other then that it works perfectly and I think if you have the time to put it in then buy it.

Hunter,

The IAG Performance V3 Street AOS can be a time consuming installation but it is well worth it! 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 this AOS eliminates this issue and keeps your motor running clean and strong! Thank you for the 5 Stars!
