CP V2 Air/Oil Separator: 2002-2007 WRX/STi with Top Mount Intercooler
The Air/Oil Separator solves a simple problem from the manufacturer; it transfers the oil back into the engine via the block not the intake. This not only keeps the vehicle within specs of smog but keeps the oil from coating the tops of the pistons. We all know what that does to any tune you have; it causes detonation, a very bad thing for turbo engines.
So if you want to keep your engine running consistently and strong for years to come make sure you install a race and street proven product from leaders in the industry.
The newest version of the air oil separator features a coolant line pass system, which helps the unit run more efficiently in cold climates or short trips. Making this ideal for any street going car, or full blown race car!
This AOS is only for stock location turbos. It will not work with rotated mount setups.
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. That being said, it can definitely be done at home with a few simple tools.
