Part# S07141. This is a clearance listing. Note that some parts are missing, including hardware, hose clamps, mounting bolts, zip ties, a rubber cap, a steel pipe plug, and a crank case connector breather Y. The kit seems to be unused with just some minor cosmetic damage. Clearance items cannot be returned. This Crawford Performance Single Chamber Air Oil Separator (V2) is designed for use with a Top Mount Intercooler (TMIC). It fits 2002 - 2007 Subaru WRX, 2002 - 2007 Subaru STi, and 2004 - 2006 Subaru Forester XT. Unlike a catch can, it's a closed - loop and maintenance - free system. It helps you consume less oil, extends your engine's life, reduces detonation and the risk of engine/ringland failure, and cuts down on fuel dilution and power loss. With the Crawford Air Oil Separator, you can stop oil from pooling in your intake. Crawford Performance was the first to create a system specifically for Subaru's oiling issues, and no other AOS on the market uses the same technology.
Using this Crawford Air Oil Separator is easy. First, make sure your vehicle is one of the compatible models: 2002 - 2007 Subaru WRX, 2002 - 2007 Subaru STi, or 2004 - 2006 Subaru Forester XT with a Top Mount Intercooler. Install it according to the standard installation process for such parts. Keep in mind that this is a clearance item, so it's non - returnable. Also, it's missing some parts like hardware and hose clamps, so you may need to source those separately. As for maintenance, since it's a closed - loop and maintenance - free system, you don't have to do much. But it's a good idea to check it occasionally for any signs of damage or abnormal operation. If you notice any issues, consult a professional mechanic. This separator will help your engine consume less oil, last longer, and perform better, so take good care of it and enjoy a smoother driving experience.
