Radium Engineering Universal Air Oil Separator (AOS-R)

For a properly planned performance build, the Radium Engineering Universal Air Oil Separator (AOS-R) separates oil mist and blow-by contaminants from crankcase vapors while allowing collected oil to return to the engine where the system is designed to do so. It is a clean way to reduce oil carryover through the intake on a modified or hard-driven engine without relying on a collection of universal hoses and brackets.

This is a universal component, so final placement and surrounding plumbing depend on the way the rest of the system is built. Confirm vehicle fitment, crankcase return routing, and any left-hand/right-hand-drive restrictions before installation.
