Radium Air Oil Separator (AOS) - 2013-2016 Scion FR-S / 17-21 Toyota 86 / Subaru BRZ

Radium Air Oil Separator

A high powered modified engine tends to generate excessive blow-by oil and gasses. In these cases, an ordinary small catch can may quickly fill with oil and not be adequate. Like the Radium Engineering Catch Cans, the AOS (Air Oil Separator) kit is responsible for keeping blow-by oil and other pollutants out of the air intake and intercooler (if equipped) systems. The main difference is that an AOS system returns collected oil back into the oil pan so there is no servicing required.

Tons of benefits you'll see with Radiums AOS. Effectively raises the octane and increases engine performance with cleaner inlet air. Prevents oil buildup in the intake or intercooler system walls, throttle body, intake manifold, etc. ad evem lowers hydrocarbon emissions.
