yes...and no. if you want to use all oem parts and have everything bolt right up nice and perfect, then i'm pretty sure you need it. if you don't mind doing a little custom fab i am almost positive the only areas you will need to modify are on either side of the front grill, where the front bumper is attached with the cheap ass plastic philips screw expander things. the front grill should line up fine with all 5 holes, but the 2 holes in the bumper are a little off. (was this way with my wings west bumper, not sure about oem, but i would think they would be the same?).
