i'll tell you what others have told me... get a custom-fit grille, but be prepared for a possible rise in temps... apparently people have been getting GM to pay half as well (search the forums) but, I bought the Mr. Grille billet grille at customcargrilles.com for about $100, figure if it rises temps too much i'll take it off during the summer, but in the mean time, it's a great way to protect the area. Again, search around on the forums, theres info out there...
best of luck, congrats on your purchase!
