I have had two new sets of grilles. One matte black and the other was the Glossy Black. (Both from Khoalty.)
Not sure if they don't attach correctly to my hood (which a lot seem happy with theirs) or I am just stupid when it comes to installing them.
Both very loose. If you don't want a black kidney grille you can buy used from a member here or just pay whatever exorbitant amount for a new set from the dealer.
