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. 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.
