New to ALP, advice on install Audi S4

Ok, thank you. I will see what other ways I can work with this grill. You are correct, I think I will have to trim the grill to fit the Priority Sensors.

The reason you can't have a combination of plastic & air space in front of the NET RADAR is b/c they are 2 different mediums. When the radar wave hits plastic & open space of air it causes distortion in the radar signal & loss to the wavefront entering the aperture of the antenna Horn. End result means lower sensitivity to the Detector. All air or All plastic is best...but never both in any combination !
