Large Breather Port For Maximum Ventilation.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. These heating system upgrades will allow for a cleaner installation and less condensation buildup in colder climates. 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. The most popular Subaru AOS for Competition use is now even better! The IAG AOS body is completely redesigned using cast aluminum and features an integrated coolant passage for better heat retention. IAG’s V3 AOS also eliminates the OEM PCV valve which is known to fail in high horsepower applications. All oil in the CCV systems is prevented from entering the intake tract.
The Competition Series vents the PCV gases to the atmosphere via a large 1” diameter vent hose. 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. Once the oil reaches the intake tract it will directly enter the intake manifold and then the combustion chamber of the engine. This oil may cause premature failure of rubber or silicone hoses, which leads to failed connections. First, the oil coats the internal portions of the intake, intercooler, and piping. Oil in the intake tract of the engine has several detrimental effects.
Keeping oil out of the engine intake tract is extremely important towards preventing premature mechanical failure and maintaining performance. Please consult a tuner for more information.
The Competition Series AOS may require additional tuning calibration. The Competition Series AOS is best suited for Drag Racing, Road Racing, and high horsepower Competition applications looking for superior crankcase ventilation. The AOS’s fully-heated cast aluminum housing, superior venting, and unique, patent-pending, baffle design set it apart from the rest. The large, 1-liter, cast aluminum swirl pot canister collects the oil from the PCV system and allows it to drain away before the PCV gases are vented to the atmosphere, preventing all oil from reentering the intake tract. The Competition Series AOS design is based on years of extensive testing on racing and high horsepower Subaru s. The Competition Series AOS keeps oil out of the intake system of your engine by venting crankcase vapors into the atmosphere. The IAG Performance V3 Competition Series Air / Oil separator (AOS) is an excellent investment to keep your Subaru Competition Vehicle running well. NOTE: Street version of this AOS found HERE. IAG recommends the Competition Series AOS for Competition vehicles with greater than 600 WHP output. I also have a low mileage 2004 STI steering wheel and a super rare, never installed LNR lip that can be included if the price is right.Competition Series AOS’ are “Competition Only” components for installation exclusively on “Competition” vehicles or “Racing” vehicles not subject to pollution control.
However there is a small beginner's spot that I just noticed on one of the front fenders due to a slit in the paint where it meets the front bumper.įeel free to message me if you have any questions. This is a Texas car that followed me when I moved out here, and was only really driven thru 2 winters so it has far less rust to deal than your typical East Coast Subaru. I would re-tint the rear window if I were keeping it as it just recently start to give way due to age. Last year it was tuned by Junior at IAG on 93 and made 430 whp and 370 ft lbs of torque.Īs it is 15 years old, it does have its dings, rock chips, etc. All fluids have been recently changed out except transmission and rear diff, which were done 15k ago. The engine has roughly 1,500 miles on it, it has brand new wheels and the RE-11s were just mounted and have less than 100 miles on them, and the suspension went on right before the engine build. Many of the major components are brand new. The parts list on this car alone is enough to buy a 2017 STI.
Instead it largely sits in my garage still accumulating thousands more in mods that I'm not taking advantage of (everything in green on the mods list photo has 3,000 miles or less on them).
It was a daily driver until 2007 and has not accumulated any real miles in the last few years. I am the second owner and have owned it since 2003.
