Radium Air Oil Separator Kit for WRX & Forester XT

This Radium Air Oil Separator Kit is specifically designed for high-powered modified Subaru engines, such as the FA20F engines found in the 2015-2021 Subaru WRX and 2014-2018 Subaru Forester XT. Engineered to combat excessive blow-by oil and gasses, this kit is essential for maintaining optimal engine performance and preventing potential damage. Unlike ordinary catch cans, the AOS system returns collected oil to the oil pan, eliminating the need for servicing and ensuring a seamless operation. The built-in heater effectively prevents water condensation, while the integrated water trap ensures that any water is trapped and evaporates out of the system, further protecting your engine.

Key Features:

  • Machined aluminum construction for durability and precision
  • Completely disassemblable for easy cleaning and maintenance

Unmatched Benefits for Enhanced Performance

With this AOS kit, you can expect significant improvements in engine performance and efficiency. The system effectively raises fuel octane, resulting in cleaner inlet air and a more powerful engine. By preventing oil buildup in critical areas like the intake manifold and intercooler system walls, this kit helps to lower hydrocarbon emissions and extends the lifespan of your engine. The kit is designed to install on the LH side of the engine bay, near the brake master cylinder, and requires the Radium Brake Master Cylinder Brace for installation. The custom machined adapter fitting replaces the PCV valve, ensuring that the collected oil drains out the bottom fitting and back into the engine block. This comprehensive kit includes all necessary components for a hassle-free installation.

Kit Contents:

  • Machined aluminum Radium Engineering Air/Oil Separator
  • Specially designed mounting bracket
  • All necessary SAE J30R7 rated PCV/Emissions hose
  • Coolant hoses and fittings
  • PCV delete fitting
  • All necessary aluminum fittings and hose-ends
  • Stainless steel mounting hardware
  • 20-0255 Master Cylinder Brace (required for installation)
