Its to breath, it goes where something needs to breath, you attach it.

Not to sound like an a*s, but it really is that self-explanatory.

Back in the day, they were on the valve covers of almost every American V8 to allow the crankcase to breath. Not all pimped out like the photo but the same thing in principle.
I've got installed on the end of my BOV (I converted stock BPV ghetto style) of arguable benefit.

Positive crankcase ventilation system?

The valves started popping up in the 60's. Prior to that most breathers were basically a 'catch can' with a tube pointed down.
We'd pull the valves because at higher RPMS(4500+) they did not allow enough air to move through the system. Made for a messy engine bay, but on the plus side, never had any rust either.

Just leave the stock system on the 2.3i you have. It is just fine. Those are even a joke on the ricer cars.
