I'm happy with my dealer installed RGS grill screens but... if I did it again, I would do them myself. After a small bird flew into, and then died and stunk, in the front of my new Honda Ridgeline Trailsport, I just made some screens from 1/4" fencing and outdoor use all weather cable ties from a hardware store. Some folks use gutter guard mesh for a slightly different look. I must admit I was a bit more intimidated to remove the front bumper assembly and rocker panels, like my tech did at the dealer, on my Porsche than I was the Ridgeline but YouTube videos showed me that it was very doable. Make sure you have the plastic pry tools to loosen your body panels and take it slow
. I got those from RGS but they may have them at your local auto parts store.
