I built a custom intake for my XF the other day. Here it is before and after:

AFTER

I'm extremely happy with how it turned out. It's a tight fit but looks and sounds great. The blower is bit louder like I was hoping for. The stock intake boxes have K&N filters in them and they are known to be more than sufficient so I'm leaving them for now. I'm probably going to swap on a different supercharger pulley to get a few more HP. It is a fun summer daily driver so I'm not going to do anything crazy with it.
