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.

With optional add-ons like our AOS drain back kit and AOS coolant add-on kit, our AOS will fit your specific needs without an issue.

Note: Anodized parts can potentially fade over time due to engine bay heat.
