Compact Iag Air Oil Separator Aos For 08-14 Wrx 08-21 Sti 09-13 Fxt 05-09 Lgt & Obxt -neon Yellow - Don't Miss Out [WLJ6EMjo]

The IAG Performance Air / Oil Separator (AOS) is a smart upgrade for your Subaru. Developed through years of meticulous testing on standard and competitive applications, the design of the AOS offers unparalleled protection for your engine. This AOS features a 1-liter swirl pot canister made of cast aluminum. This construction significantly enhances the separation of oil from the PCV system before the PCV gasses are directed back to the intake system. The Air Oil Separator features an aluminum housing that has superior ventilation, and it incorporates an exclusive baffle design that sets it apart from the competition. The IAG AOS works with all fuel types, optimizes crankcase ventilation, and seamlessly integrates with standard ECU settings, so no tuning is required. The IAG AOS is designed for effortless upkeep. Unlike typical catch-can systems, our Air Oil Separators operate without the need for routine draining and maintenance. Separated oil gathers on AOS can walls and slowly drains into the engine's crankcase. With the help of our unique heating system, the collected oil remains free of sludge, ensuring that there is no risk of reintroducing it into the engine. The substantial size of the AOS body allows for a safe and gradual oil drainage process, effectively removing the chance of overflow commonly observed in smaller catch cans.
  • Keeps oil out of your intake for improved performance.
  • Unique baffle system that captures the oil suspended in your engine's PCV gasses, which are then able to drain back into the crankcase.
