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.

There you can also find a full fitment list for all current versions and kits.

Note: more V3 fitment options are currently in R&D. Is your car or application unavailable? Click here to check our V2 Kits, which have the widest range of fitments. 

*Note: Due to the fact that the AOS bracket connects to the TGV housing, this kit is not compatible with aftermarket TGV housings.

*Note: This system was designed on USD models. Not compatible with all PCV systems across the world and may require some additional components to properly install.
