Radium Engineering Air Oil Separator (AOS) Return Kit for 2015-2020 Subaru WRX STI (20-0607)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2020 Subaru WRX STI (Base, Launch Edition, Limited, Series.HyperBlue, and Type RA).
The Radium Engineering Air Oil Separator (AOS) Return Kit is a critical engine health upgrade for the late-model Subaru STI platform. This system intercepts oil vapor and combustion byproducts before they can enter the intake manifold, preventing intercooler contamination and reducing the risk of oil-induced detonation. Unlike sealed catch cans, this return-style system is designed to drain captured oil back into the crankcase, and the canister is fully serviceable for long-term maintenance.
- Full kit includes all necessary hoses, brackets, and hardware for a complete installation.
- Serviceable canister design allows for easy internal inspection and cleaning.
- Helps maintain fuel octane levels by reducing oil ingestion into the combustion chamber.
- Keeps the intake tract and intercooler free of oil sludge buildup.
- Manufacturer Part Number: 20-0607
