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

Our AOS has one job and that is to remove the oil from the engine crankcase system so the oil does not get into the intake system. Oil in the system reduces octane, which can lead to detonation, reduction in power, and carbon build-up.
