OPEN BOX - IAG Street Series Air Oil Separator - AOS - Black (15+ WRX)
The IAG Performance Street Series billet aluminum Air / Oil separator (AOS) vents crankcase gasses back to the turbo inlet. The design is based on years of service on racing and high horsepower Subaru's. The AOS's approximate 1-liter capacity, fully heated housing, superior breathing, and unique patent pending baffle design set it apart from the rest.
