Product Overview
Radium Universal Air Oil Separator-Return (AOS-R)
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.
IMPORTANT INSTALLATION NOTES:
-In order for the AOS to function properly, a port must be supplied on the engine for the oil to return through.
-The AOS must be mounted high enough in the engine bay so that the port on the bottom is higher than the oil return port on the engine.
-for heating purposes, engine coolant must be routed to the AOS-R to prevent condensation.
Benefits
-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.
-Lowers hydrocarbon emissions
