BM is correct..... if you're discussing the removal of the solid plastic pieces on the lower grille openings, simply for cosmetics reason(s), you may want to reconsider.
Particularly if your veh's equipped with the ACC option. But then again, depending on where you live, it might not even be a real, true concern.
What needs to be kept in mind, is premature over exposure of the ACC sensor, to the elements of Mother Nature.
Of course, where there's a will, there's always a way.
Perhaps if you, or someone you know, possesses mad PS skills, have someone fab up a couple of images of what you'd like to do, then proceed from there.

Good luck!
