Description

2015+ Subaru STI Radium Engineering Air-to-Oil Separator (AOS) – Part Number 20-0607

Upgrade your Subaru STI’s engine ventilation system with the Radium Engineering Air-to-Oil Separator (AOS). Designed for performance-focused Subaru owners, this component helps separate oil from crankcase ventilation gases before they can circulate back into the intake system.

Whether you’re maintaining your Subaru STI or upgrading your performance setup, this Radium AOS is a useful component to consider for your build.
