Radium Engineering Air Oil Separator Return Kit

The Radium Engineering Air Oil Separator Return Kit is a cutting-edge solution designed for high-performance vehicles like the Scion FR-S, Subaru BRZ, and Toyota GT86/GR86. This kit is engineered to effectively manage blow-by oil and gases, ensuring optimal engine performance and longevity. The core feature of this kit is its ability to separate air and oil, preventing contamination in critical engine components.

Technical Specifications and Features

The AOS-R Air Oil Separator boasts impressive dimensions and specifications. It measures 6.3" in height and has a diameter of 3.45" for a robust design. With a capacity of 20.3 oz (600mL), it provides ample space to collect blow-by oil and gases without frequent maintenance. The kit includes a variety of ports for optimal installation and compatibility. The inlet, outlet, and return ports are all 7/8"-14 threaded for 10AN ORB fittings, while the coolant ports are 7/16"-20 threaded for 4AN ORB fittings. This ensures seamless integration with your vehicle's existing systems.

Practical Benefits and Applications

The Radium Engineering Air Oil Separator Return Kit offers numerous practical benefits for both daily driving and track use. By effectively managing blow-by oil and gases, it prevents oil buildup in critical components such as the intake, intercooler, throttle body, and intake manifold. This not only improves engine performance but also lowers hydrocarbon emissions, contributing to a cleaner environment. The built-in heater prevents water condensation, and the integrated water trap ensures that any excess water is contained within the separator. This kit is an essential addition for any enthusiast looking to maximize their vehicle's performance and maintain a clean, efficient engine.
