Features & Product Details

RallySport Direct now carries highly sought-after high-performance upgrades and accessories brought to you by IAG Performance.

This is the IAG Performance V3 Street Series Air / Oil Separator. This latest design prevents harmful oil or vapors from coating your intake system which can lead to a lack of performance and long-term engine damage.

RED CATCH CAN FINISH OPTION

KEEPS OIL OUT

Keeping oil out of the engine intake tract is extremely important in preventing premature mechanical failure and maintaining performance

Prevents oil from coating the internal portions of the intake, intercooler, and piping

Prevents premature failure of the rubber or silicone hoses, which can lead 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

PCV RECIRCULATION:

The Street Series maintains the OEM PCV system functionality but supplements its capacity

The AOS PCV discharge gasses return to the turbo inlet, retaining a PCV valve to draw additional suction, improving air oil separation

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

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

VERSION 2 VS. VERSION 3 AOS:

The IAG AOS body is completely redesigned using cast aluminum and features an integrated coolant passage for better heat retention

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

THE TOP OF THE BODY:

True 360 Degree Rotating Breather Port

Dual Breather Ports

Greater Pressure Stream Oil Separation

As air and particles of oil enter the AOS, the largest particles of oil will collect on the inner surface of the can and drain to the bottom, but the smallest particles will remain suspended in the pressurized stream

As the air makes its way through the multi-stage baffle system, gravity pulls oil from the air

By increasing the overall volume of the breather opening on the top of the AOS, IAG has drastically decreased the exit velocity of the crankcase vent (CCV) stream

The slower velocity leads to greater oil separation from the pressure stream

A total of 20 mounting holes enable the breathing port a full 360° of rotation

On the top, a thick Viton o-ring seals the can. Every o-ring in our AOS is formed from Viton which offers superior temperature and chemical resistance

AOS MAIN BODY:

Compact Cast Aluminum Design

Approximate 1 Liter Holding Capacity

Integrated 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

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

Reduces the overall system pressure

AOS BOTTOM OF THE BODY:

Unique Baffling Controls Crankcase Pressure

Returns Oil To The Engine

No Maintenance or Manual Draining Required

The bottom of the AOS is shaped like a snail, redirecting positive crank pressure into the same swirl pattern produced by the 3 side ports

Allows maximum oil drainage, while separating oil from the air in all the venting ports

AOS DRAIN PORT:

The AOS drain port is able to be rotated for ease of installation, as well as pre-threaded to accept an ORB fitting if desired

AOS FITTINGS:

Includes all fitting required for installation

Includes unique billet aluminum coolant swivel fittings

AOS HOSE:

The supplied coolant hose is built to SAE 30R9 standards

It will withstand coolant temperatures of +257°F

The oil vapor hose is designed to withstand oil and fuel vapors, exceeding SAE J30R7
standards

AOS COOLANT:

Heated By Engine Coolant

Reduces Moisture & Oil Mixing

Features an integrated coolant chamber that heats the entire AOS to the same temperature of the engine

This cast aluminum can hold more heat which maximizes the evaporation of any condensation collecting inside of the can

The hotter the AOS, the less condensation will collect inside and mix with the oil

AOS MOUNTING:

Multi-point adjustable mounting bracket

If your engine bay changes, you can easily change how and where you mount the AOS

The V3 AOS body features a greater number of mounting holes enabling a wider range of adjustments

A single, laser-cut, mounting bracket is included that fits nearly all applications and configurations

A laser-cut harness relocation bracket is also included that allows the engine harness connector to be moved forward for additional clearance

AOS IN THE BOX:

Ready To Install

Hardware, Lines & Fittings Included

The AOS arrives completely assembled and ready for immediate installation. However, the entire unit can be broken down for cleaning with a single Allen wrench, you can remove two bolts and the AOS easily separates into individual pieces

Didn’t buy from here but got one from someone else brand new in box, for the price I would expect better clamps and better instructions. Good think for YouTube I found a decent video and the guy uses zip ties on everything instead of the clamps lol. I used both here and there had 2 leaks and fixed them with zip ties.The YouTube video also shows them jumping the blow by sensors (I did the same I hope that wasn’t a mistake lol). I hope the blender screw in the aos is enough to bleed the cooling system after removing the coolant lines from turbo. We’ll see how this holds up and hopefully my car doesn’t blow up lol

Best AOS 2 years ago

IAG makes the best AOS for your EJ Subie. It's one of the most expensive AOS because you get what you pay for. The unit is absolutely top-quality. You won't have any regrets once you feel the quality of this AOS. Best part is that you don't have to empty it like a catch-can. So once it's installed, you are all set!
