Default Adding Passive PFC coil to PSU?

So I want to swap another PSU into this unique case that has had the original guts fail. The PSU case was designed for a PPFC coil, so I'd like to incorporate it into the drop in.

So I really can't remember. Can't you just drop in the PPFC coil? Most PCBs are labeled for them but I really can't remember. There isn't any circuitry that needs to be added? The one in question has a polypropylene capacitor attached to it:

Would I just install this where the circled jumper is?

How much does the coil improve the PFC %, realistically?

I will make a separate thread for the case replacement.
