Verus Air/Oil Separator Kit, 2015-2021 WRX

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. Using coalescent filters, we are able to filter out oil vapor down to 5 microns in size.
