UPR Clean Side Separator (CSS):
This Clean Side Catch Separator is especially beneficial to modified vehicles with added Superchargers or Turbo kits. As crankcase pressure builds up under BOOST, it will be forced out of the driver side valve cover fitting. This clean side separator will still allow clean air to enter the crankcase as the factory intended, but will catch oil and impurities when crankcase pressure is high, preventing that gunk from getting into your cold air kit and throttle body. Once normal driving resumes, the Clean Side Separator will allow the oil mist to return to the crankcase.
Made in the USA!
Well built, and easy to install. Installation instructions were very helpful. Cannister is easy to access and empty.
