Product Details

The RADIUM Engineering AOS-R (Air Oil Separator) Kit is a complete solution designed specifically for 2009-2013 Subaru XT, 2008-2014 WRX, and 2015-2021 STI models. This system effectively separates oil vapor from crankcase gases before they re-enter the intake system, helping to keep intake components cleaner and maintain optimal engine performance.

Key Features:

  • Complete bolt-on kit includes all necessary hardware and components for installation
  • Fully serviceable design allows for easy maintenance and cleaning
  • Baffled chamber design maximizes oil separation efficiency
  • CNC-machined aluminum construction with anodized finish for durability
  • Integrated dipstick allows for easy oil level monitoring
  • Direct-fit application requires no permanent modifications to the vehicle
  • Helps reduce carbon buildup on intake valves and intercooler cores

This air oil separator system is engineered to work seamlessly with the Subaru boxer engine's positive crankcase ventilation system, providing a reliable and effective method for maintaining engine cleanliness while preserving proper crankcase pressure. The kit includes all necessary brackets, hoses, fittings, and hardware required for a complete installation.

Awesome look forward to buying more!

I did a lot of shopping around and they had the best price, by a good amount, even having to pay for shipping. Parts arrived in a timely manner, but the box they were shipped in didn't look up to the task of the weight of the parts being shipped, the exterior packaging was crushed at one end and partially opened. No damage to the parts or their manufacturer packaging was observed. The parts were as advertised except one of the Bilstein 22-001856 Twintube strut's hardware kits was packed incorrectly at the original manufacturer. It was supposed to have two short wheel assembly mounting bolts and one long wheel assembly mounting bolt and nut combo. It contained the right number of washers and nuts, but I only received one short bolt and instead got one extra long bolt. I didn't notice this until I was ready for installation, so I reused one of the old bolts I had removed. Not ideal when the plan was to refresh hardware. Overall I was satisfied with Autoplicity and will continue to shop with them.
