Default Valve cover breather

I was looking at parts and I came across this part and I don't understand what it actually does, I have been searching and I was just wondering if this would be helpful to put on my car, and also where exactly it mounts. Sorry if im being a little dumb here Im just a little confused

Most guys use those breather when they delete the PCV system, I've got two on my car

if you are leaving your pcv system in tact then no you don't need them.

A metco breather is still beneficial even when you do run a PCV system. It vents crankcase pressure which is a good thing.

okay thank you for clearing it all up for me, the only reason I was interested in it was because I hear that it can help your engine run a little better and what not, and they arnt expensive.

They vent crank case pressure which can lower oil consumption which is a common problem. We sell the Metcos on our web site
