IAG Air Oil Separator AOS for Subaru

The IAG Performance Air/Oil Separator (AOS) is a revolutionary upgrade designed specifically for Subaru vehicles, including the WRX, STI, and FXT models. This advanced separator is the result of years of meticulous testing and development, ensuring that your engine receives unparalleled protection and performance enhancement. Engineered to integrate seamlessly with your Subaru's existing systems, the AOS is a smart choice for any Subaru enthusiast looking to maximize their vehicle's potential.

Key Features and Specifications

The IAG AOS boasts a 1-liter swirl pot canister made of cast aluminum, which significantly improves the separation of oil from the PCV system before the gases are returned to the intake. This innovative design, combined with an aluminum housing with superior ventilation and an exclusive baffle system, sets the IAG AOS apart from the competition. The separator is compatible with all fuel types and optimizes crankcase ventilation without requiring any tuning. Here are some of the key features and specifications:
  • 1-liter Swirl Pot Canister: Made of cast aluminum for enhanced oil separation.
  • Aluminum Housing: Superior ventilation and exclusive baffle design.
  • Universal Compatibility: Works with all fuel types and integrates with standard ECU settings.
  • Easy Maintenance: No routine draining and maintenance required.
  • Practical Benefits and Uses

    The IAG AOS is not just a performance upgrade; it's a practical solution for maintaining your Subaru's engine health. By keeping oil out of the intake, the AOS improves performance and reduces the risk of engine damage. The unique baffle system captures oil suspended in the PCV gases, allowing it to drain back into the crankcase safely. This process is facilitated by a unique heating system that keeps the collected oil free of sludge, eliminating the risk of reintroducing it into the engine. The substantial size of the AOS body ensures a safe and gradual oil drainage process, effectively removing the chance of overflow. Here are some of the practical benefits and uses:
  • Improved Performance: Keeps oil out of the intake for enhanced engine performance.
  • Engine Protection: Captures and safely returns oil to the crankcase, reducing engine wear.
  • Easy Installation: No tuning required and integrates with standard ECU settings.
  • Longevity: Ensures the longevity of your Subaru engine with minimal maintenance.
