The Crawford Performance Air Oil Separator (AOS) is the original solution to Subaru's notorious oiling system issues. Although the technology was pre-existing with other vehicle brands such as Porsche, Crawford Performance is the inventor of the first system specifically for Subaru. No other AOS on the market employs the same technology.
