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 Dual Chamber AOS (V3) is our best yet – developed with the consumer in mind. It is easier to install than the Single Chamber AOS (V2). It also utilizes the OEM PCV Valve and leaves every smog component intact. This makes the product smog legal and allows for use in both on-road and off-road vehicles legally, unlike the Single Chamber AOS (V2).
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.
