Cobb Air Oil Separator - Fits 02-07 Subaru WRX / 04-07 STI
Cobb 02-07 Subaru WRX / 04-07 STI Air Oil Separator
The COBB Air/Oil Separator is placed within your Subarus crankcase ventilation system and helps to prevent oil vapors from being introduced into the intake system. The COBB Air Oil Separator has been developed in partnership with IAG Performance and offers exclusive features.
The COBB Subaru Air/Oil Separator helps to prevent crankcase oil vapors from recirculating back through your engine's intake system.
Oil vapors passing through your engine's intake system lower the effective octane rating of fuel and can contribute to both oil and carbon buildup over time.
COBB's revolutionary Double Adjustable Shifter ushers in a new generation of adjustability for one of the most critical links from driver to car, the ability to control both the height of the shift knob as well as the length of the shifter throw. This shifter has a "wide barrel" and is for use in cars that did not come with the Subaru factory short-shifter option.
Note: This AOS can be installed to 2002-2005 WRXs with modification to or relocation of the Cruise Control Module.
