Cobb Air/Oil Separator (822615)
The COBB Air/Oil Separator is integrated into your Subaru's crankcase ventilation system to prevent oil vapors from entering the intake system. Developed in partnership with IAG Performance, it features a 1-liter holding capacity, integrated ORB ports, a compact cast aluminum body with a wrinkle black powder coat finish, heat shielding on the crankcase breather and oil return lines, a coolant bleeder valve, bespoke COBB color combinations, and a laser-etched COBB logo. The bottom of the AOS is snail-shaped to redirect positive crank pressure into a swirl pattern for maximum oil drainage, while a backplate coolant routing system heats the can to minimize water collection and oil mixing. It is 50-state legal for emissions-controlled vehicles with CARB EO numbers D-660-25 and D-660-45.
Emissions Note: 50 State Legal. This part is legal for sale and use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it has CARB EO numbers D-660-25 and D-660-45.
