Review on Enhance Engine Performance with Ford Racing M-6766-A50 Oil-Air Separator by Mark Adams

Revainrating 5 out of 5

Perfect fit for 2016 F-150 5.0L.

Very easy installation. I literally put it on the truck in 2 minutes. If you have one of the engines that uses a lot of oil, replace the stock PCV valve to fix the problem, then install an oil separator. The benefit of using this separator is that it looks like a standard part. The bad part of the design is that you have to use turkey tincture to drain it since it doesn't have a drain plug.

Pros
  • Fuel system
Cons
  • High price
