IAG Air Oil Separator AOS for Subaru Models

The IAG Air/Oil Separator AOS is a revolutionary upgrade for your Subaru vehicle, designed to enhance performance and protect your engine. Engineered through extensive testing, this AOS provides unparalleled protection for your 2002-2007 Impreza WRX, 2004-2007 STI, or 2004-2008 Forester XT engine. Its 1-liter cast aluminum swirl pot canister significantly improves oil separation from the PCV system, ensuring that your engine receives clean gasses and maintains peak performance. The AOS design features a lightweight yet durable aluminum housing, offering improved ventilation and an intelligent baffle system that sets it apart from other air/oil separators on the market.
  • Enhanced Engine Protection: The AOS prevents oil from entering the intake, improving overall engine health and longevity.
  • Smart Baffle Design: Captures suspended oil in PCV gasses, allowing it to drain back into the crankcase, maintaining clean air flow.

Technical Specifications and Features

The IAG AOS is constructed from a lightweight, yet robust aluminum housing, ensuring both durability and efficiency. It is compatible with all fuel types, seamlessly integrates with standard ECU settings, and improves crankcase ventilation without requiring routine draining or maintenance. The separated oil collects along the walls of the AOS canister and gradually drains into the engine's crankcase, eliminating the risk of overflow commonly seen in smaller catch cans. The oversized AOS body and exclusive heating system ensure the gathered oil remains free of sludge, reducing the likelihood of reintroducing it back into the engine.
  • Compatibility: Works with all fuel types, compatible with Subaru models listed.
  • Heating System: Ensures collected oil remains free of sludge, prolonging engine life.

Practical Benefits and Target Audience

The IAG Air/Oil Separator AOS is perfect for Subaru enthusiasts seeking to maximize their vehicle's performance and longevity. Its unique features make it an ideal upgrade for daily drivers, track enthusiasts, and those looking to restore their Subaru to its original performance specifications. By keeping oil out of the intake and improving crankcase ventilation, the AOS helps to maintain engine efficiency, reduce emissions, and enhance overall driving experience.
  • Performance Enhancement: Boosts engine performance and reduces emissions.
  • Target Audience: Subaru owners looking to enhance their vehicle's performance and maintain engine health.
