Just thought I'd toss this out. We live in the country and bugs (grasshoppers) go right in when louvres open and end up on the condenser. Used some hex aluminum mesh grille material (Ebay, and many other places to get it) and bordered it with smallest wiper fluid hose to cover the sharp edges (there are better ways to cover edge). I did it to keep out bugs, but now I have grown to like the look. It tones down the chrome in the vents. almost forgot to mention how I attached it (also many better ways to do it), I used 2 wire ties, top left and bottom right to go around the chrome strip.
