The bottom of the heat shield screws into the frame rail (?) instead of using the grommets that the stock airbox uses. See Akrion's photo - you can see one of the stock grommet holes and a tab for the USP heat shield - there is a self tapping screw right there in the center of the black tab.

Your install seems to have the same gap around the intake tube and heat shield as mine did before I added a filler panel. I thought maybe it was a B8 vs. B8.5 thing or maybe S4 vs S5... guess not. I feel a little better - USP told me it was just a matter of rotating the intake tube, but everything I did seemed to make it worse someplace else.
