Crawford TMIC v3 Air Oil Separator (Black) - Subaru STI VA


- +


Fits 2008-2020 Subaru STI and 2008-2014 WRX

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.

The V3 is our best yet – developed with the consumer in mind. It is easier to install than the V2, and now utilizes the OEM PVC system making it smog legal.

This kit includes the can itself, and all necessary hoses and fittings to install. The install does take some mechanical knowledge, so we suggest taking your car in to a professional for installation. That being said, we provide step by step instructions so that enthusiasts can install the kit at home with a few simple tools.
