Description
The COBB Tuning Air Oil Separator (AOS) is designed for the 2008-2014 Subaru WRX and 2008-2020 Subaru STI to help separate oil and other contaminants from crankcase vapors before they are returned to the intake system. This helps keep the intake tract cleaner while supporting proper crankcase ventilation on turbocharged Subaru engines.
The COBB Air Oil Separator is designed as a vehicle-specific solution for Subaru performance applications, making it an ideal addition to modified and tuned vehicles.
