Product Information

Radium Engineering's AOS-R kit separates oil from crankcase vapor and returns it to the oil pan, keeping oil out of the intake, turbo, and intercooler with no draining required. The machined aluminum separator holds 20.3 oz (600 mL), uses a coolant heated core to prevent water condensation, and has an integrated water trap around the bottom perimeter. The unit is fully serviceable, and the kit includes a Subaru specific mounting bracket, SAE J30R7 rated PCV hose, coolant hoses, and all fittings and hardware. Not compatible with right hand drive vehicles.
