With this separator, you'll consume less oil, extend your engine's lifespan, reduce detonation and the risk of engine/ringland failure, and minimize fuel dilution and subsequent power loss. Say goodbye to oil pooling in your intake. The Crawford Air Oil Separator is the original solution to Subaru's well - known oiling system issues. While similar technology exists in other brands like Porsche, Crawford Performance was the first to create a system specifically for Subaru, and no other AOS on the market uses the same technology.

Using the Crawford Air Oil Separator is easy. First, make sure your vehicle is turned off and cooled down. Locate the appropriate connection points for your 2002 - 2007 Subaru WRX, STi, or 2004 - 2006 Subaru Forester XT with TMIC. Connect the separator according to the included instructions. It's a closed - loop system, so you don't have to worry about emptying it like a catch can. As for maintenance, since it's maintenance - free, there's not much you need to do regularly. However, it's a good idea to check the connections every few months to make sure they're secure. If you notice any signs of oil leakage or a decrease in performance, have it inspected by a professional. By using this separator, you'll save on oil costs and keep your engine running smoothly for longer.
