Anything that helps minimize pcv oil vapor condensation inside the intake is a good thing IMO. The minor extra maintenance of dumping the condensed oil, cleaning the filter element with carb cleaner every 5k miles or so, and checking connections is trivial for most Mustang enthusiasts.
I agree. And I'm also grateful for the video post. I know it's hit or miss with most people thinking these are helpful, but it has me considering one.
