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 !

Thank you. Any thoughts on where I might install the radar?

Most of my above PSL driving is on the Interstate highways, so I bias my RDs to the Driver side of the vehicle Front. Even if I'm in the Right lane behind cars or Trucks I can move left & let the RD peek around whatever is in front of me to sniff the air ahead. Putting the RD in the center of your grill tends to get shadowed or block the radar signal by whatever vehicle is ahead you. Radar cannot pass thru all that metal surface of other vehicle ahead.
If the RD was a windshield mount, I put it high on the glass near the headliner (to shade it from the heat of the Sun) shining on it. Radar signal can easily pass thru the window glass of the cars ahead, but will still be blocked if it's a Big Rig w/ a 12' high metal trailer in front of you.

Driver side bias for me b/c I'm usually in the Left Lane haulin' ass !
