I was doing an oil change on my '16 FiST today, and happened to see this hose connection, with nothing connected. Does anybody know what this is for? Sorry, this was the best pic I could find online, lol.

Well, that was fast. Haha. Thanks Isaac!
But do you mind shedding some light on what's its function is/was?

It's a remnant from the N/A Fiesta. It appears to be emissions related as there is a vacuum line from there to the crankcase. For the ST, there's no actual hole there.
