Radium Air Oil Separator (Subaru)
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. Like the Radium Engineering Subaru 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 that an 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.
All Radium products are carefully planned with thorough R&D and designed in-house using the latest computer simulation and modeling techniques. Extensive testing and evaluation ensures the performance of Radium products exceed consumer expectations. For these reasons, top motorsports competitors and enthusiasts worldwide rely on Radium Engineering products.
Currently, Radium offers an expanding collection of motorsport parts and accessories for high performance and racing, focusing on their revolutionary fuel surge tank line and PCV oil catch can systems. A growing collection of application specific parts are also being created. Please contact Radium for more information.
