Genuine Parts

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. The unit installs like an OE component with no change to the tune or setup needed. The Verus AOS also filters both the crankcase vent location as well as the intake filter location, through a single unit.

Four, 5 micron, coalescent filters, one on each inlet and outlet, baffling, and stainless mesh offer unprecedented air filtration for the crankcase air.

An optional coolant hook-up kit runs hot coolant through the AOS to reduce condensation build-up in colder months.

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