Features

  • KEEPING OIL OUT - 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. 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.
  • ORB PORTS - Aluminum body is powder coated in Red or Black Wrinkle Finish. The side of the AOS features 3 -8 ORB removable billet hose barbs. The EJ engine has 3 ports that vent crank pressure: one on each cylinder head, and another on the top of the block. Each engine vent port receives its own connection to the AOS. By giving each engine port its own entrance to the AOS, IAG has allowed for more effective and faster excavation of crankcase pressure.
  • SWIRL POT - The IAG Performance 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 IAG AOS' fully-heated cast aluminum housing, superior venting, and unique baffle design set it apart from the rest. The AOS is compatible with all fuel types, extends engine life, improves crankcase ventilation and is compatible with standard ECU calibrations.
  • TESTED FOR YEARS - The IAG Performance Street V3 Air / Oil separator (AOS) is an excellent investment to keep your EJ engine running well. The AOS maintains OEM PCV system functionality, but supplements its capacity. The IAG AOS design is based on years of extensive testing on standard and competition applications.
  • AOS BODY - Compact cast aluminum design has approximate 1 liter holding capacity integrated.

  • Download the installation guide before you start.
Be sure to have the directions readily available from the iag website even if your following one of the online videos. Alot of those videos will have different modifications on the car so things will look a little different as you follow along. I've only had mine in there for a few days so far so good though. DIY time 2-5 hours. ... show more

  • Do not trust this product
The media could not be loaded. I have a 2021 Wrx Premium. To start off i think its good to add that i am an ASE certified Auto Tech. As im driving on the highway on my way home from work, i noticed that the coolant guage was higher than usual. I have the center dash screen set to Oil temp, boost pressure, and MPG. Oil temp was reading high at 235°F. Its always at 190-200. As i start heading towards a hill, the coolant temp guage spikes to HOT and get an overheating dash light. With no emergency lane nearby, i jump the curb and shut the engine off before catastrophic engine damage can occur. Waiting for a tow, i try to figure out what happened but with no lights or tools on hand, no luck. As my car arrives home with a $200 tow bill, i start to trace the coolant hoses and found the hose that leads directly from the AOS to the turbo coolant tube was loose. The provided clamp with the kit had given out and was no longer holding pressure as you can see in the attached video. Coolant had pissed out through the clamp. Ironic how i spent close to $500 for this system to better protect the engine, almost cost me an entire engine. Do yourself a favor and do not use the provided clamps. Youll thank me when you dont have to get towed to the dealer for a blown engine in which most likely they will not want to warranty as this is not an OEM Subaru part. Their excuse will be, “if this was not installed, engine wouldnt have blown”. ... show more
