Predetor(spelling?) makes a nice grille assembly that you install in the hole and it keeps rocks, bugs, and other debris out of the intake. Just make sure you order just the grill, they have a grill/filter kit for the stock air box too. Airfury is the name of that product. I am considdering this for a future mod.
FWIW, I don't run that grill and only one incident and that was extreme. I drove through some sort of insect hatch once and got a bunch of bugs inside that I had to clear out.
The radiator fared worst off though. What I really needed was a full front screen, not just a little grill for the hole.
