- Installation Instructions:
The IAG Performance Street Series billet aluminum Air / Oil separator (AOS) vents crankcase gases 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 sets it apart from the rest.
AOS Kit Includes:
- Ready To Install
- Hardware, Lines & Fittings Included
*Please note that IAG recommends the STREET SERIES AOS for ALL cars running E85 or high-ethanol fuel blends. When tuning E85, ethanol vapors tend to stay in the crankcase, which ultimately results in the oil becoming diluted and requiring extremely frequent oil changes. Pulling vacuum via the Street Series recirculating design to the inlet is ideal for ethanol tuned vehicles, and will allow the ethanol to be removed from the crankcase and burnt off as part of the combustion process.
