Oil pooling in your intake? 
Stop the oil from ever getting there with the Crawford Air Oil Separator.

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.
