Description
The Radium Engineering 2015+ Subaru STI Air Oil Separator-Return Kit is intended for performance builds that demand a more deliberate approach than simply adapting the factory hardware. It gives the installer a Radium-specific foundation for the listed application.
Why This Upgrade Matters
An oil separator manages crankcase vapor and oil carryover before it reaches the intake tract. It is useful where the engine' ventilation system needs additional oil control without compromising the intended crankcase flow path.
