Product Description
Fitment Information:
2022-2025 Subaru WRX Features: 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 unprecedented air filtration for the crankcase air. Further improving filtration is internal baffling within the AOS itself. With optional add-ons like the Verus AOS drain back kit and AOS coolant add-on kit, this AOS will fit your specific needs without an issue.
