Radium Engineering 2015+ Subaru STi Air Oil Separator-Return Kit
Take your Subaru STi to the next level with the Radium Engineering Air Oil Separator-Return Kit. This innovative system traps blow-by oil before it can be sent back to the induction system, ensuring a cleaner engine and improved performance.
The collected oil is heated by the AOS to remove moisture, then allowed to drain back into the engine block, making this a zero-maintenance system. Installation is a breeze, using factory mounting points and including all required hardware, hoses, and other items.
