if you are talking about the cobra grill insert it is about $125 at cervinis. you can buy the stalker bumper with the insert as one for i think $400 also at cervinis. i believe it bolts and also gets put on with 3mm tape.
Cobra grille inserts are nice. Should have come from the factory that way IMO. My suggestion would be to get one that is made of urethane, like Cervini's or Design Concepts, (same part).
