Review on Moroso 85485 Air Separator Mustang by Justin Metz

I never thought about it until I read about it. My 2013 Mustang GT uses 5w20 oil and it seems most of it leaks out of the PCVs into the intake. With this clever little device built into the PCV hose, it catches the oil/oil vapor that's on its way to the intake port to coat the throttle body with any sediment/deposit/things you don't need. They say 80 to 90% of the shock goes through the passenger side, so that's the side you need to install the separator on, unless you're using forced induction, you need one on both sides. It works. I've drained it several times and always get a tablespoon or two of it.
