Air Oil Separator (AOS)

• 2022-2026 Subaru | BRZ
• 2022-2026 Toyota | GR86

The Verus Engineering Air Oil Separator (AOS) ensures the intake system remains oil-free. Oil in the intake system reduces octane, which can lead to detonation, reduction in power, and carbon build-up. Four 5-micron coalescent filters, one on each inlet and outlet, baffling, and stainless mesh offer thorough air filtration for the crankcase air. Optional add-ons like the AOS drain back kit and AOS coolant add-on kit let the AOS fit your specific needs.
