Features & Product Details

RallySport Direct carries highly engineered products designed to improve the performance and longevity of your vehicle brought to you by Radium Engineering. 

 

This is the Radium Engineering Air Oil Separator R Kit. In high-powered and modified Subaru engines, they tend to create excessive blow-by with oil vapors and gasses. in these cases, a regular small catch can fill up quickly with oil and not be adequate. The AOS R kit will keep blow-by oil and other pollutants out of the intake pipe, intake manifold, turbocharger, and intercooler during all engine loads. The main difference is that the AOS R system returns what is collected into the oil pan, so no servicing is required. The built-in heater keeps water from condensing in the AOS, and because water is denser than oil, there is an integrated water trap found around the bottom perimeter of the can. This overall design prevents water from descending into the oil pan if ever present. Additionally, because the water is trapped against the heater, it will eventually boil and evaporate out of the system. 

 

 

HIGHLIGHTS:

  • The AOS is constructed of (3) CNC-machined sections that screw together and are sealed with O-rings
  • Prevents oil buildup in the intake or intercooler system walls, throttle body, and intake manifold
  • Lowers hydrocarbon emissions
  • Effectively raises the octane and increases engine performance with cleaner inlet air
  • Height: 6.3" without fittings
  • Diameter: 3.45" round
  • Capacity: 20.3 oz (600mL)
