Features:
With the Verus Engineering Air Oil Separator (AOS) you can ensure that your intake system remains oil-free. Oil in the intake system reduces octane, which can lead to detonation, power reduction, and carbon build-up. This AOS filters both the crankcase vent location as well as the intake filter location, through a single unit. Composed of four, 5-micron coalescent filters, one on each inlet and outlet, baffling, and stainless mesh, it offers unprecedented air filtration for the crankcase air. Directly installs like an OE component with no change to the tune or setup required.
An optional coolant hook-up kit runs hot coolant through the AOS to reduce condensation build-up during the colder months.
