Description


High-powered modified Subaru engines tend to generate excessive blow-by oil and gasses. In these cases, an ordinary small catch can mayquickly fill with oiland not be adequate. Like the Radium EngineeringSubaru Dual Catch Can Kit, the 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 thatan AOS system returns what is collected back into the oil pan so there is no servicing required.The built-in heater keeps water from condensing in the AOS.And because water is more dense than oil, there is an integrated water trap found around the bottom perimeter of the can. This prevents water from descending into the oil pan if ever present. Furthermore, because the water is trapped against the heater, it will eventually boil and evaporate out of the system.

The AOS is constructed of three CNC machined sections that screw together and are sealed with O-rings.
