Radium Air Oil Separator

High-powered modified Subaru engines tend to generate excessive blow-by oil and gasses. In these cases, an ordinary small catch can may quickly fill with oil and not be adequate. The Radium Engineering Subaru  AOS (Air Oil Separator) kit is responsible for keeping blow-by oil and other pollutants out of the intake pipe, manifold, turbocharger, and intercooler during all engine loads. The main difference is that an AOS system returns what is collected back into the oil pan so there is no servicing required. The built-in heater keep water from condensing in the AOS, making sure ONLY oil is returned back to the oil pan, not a milky sludge.

 

Benefits
