The Crawford Performance Air Oil Separator (AOS) is the original solution to Subaru's notorious oiling system issues.

Easy to install and not needing to run a coolant line makes this go really quick. the included instructions were great and they even include some extra fuel hose if needed to relocate the fuel line.
