Radium Engineering 2013+ Subaru BRZ / Scion FR-S Air Oil Separator-Return Kit

Radium Engineering designed the 2013+ Subaru BRZ / Scion FR-S Air Oil Separator-Return Kit as a purpose-built solution that 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 version is designed around Scion FR-S, so the mounting, routing, or connection details should be checked against that application before installation. Confirm vehicle fitment, crankcase return routing, and any left-hand/right-hand-drive restrictions before installation.
