2001 Boxster S Front bumper center cooling duct inlet trim ring removable?

[chaiyz]

I've pulled my bumper cover to do some cleaning, replacing ballast on drivers side and reinstalling mesh in front of the intakes.

I'd love to pull the front trim ring off so I can squeeze mesh between that and the plenum piece.

I had little problem getting the side inserts out and meshing them. It's all moch'd up as I'm going to pull it apart again and fill paint chips and repaint.
