I installed the OEM Infiniti hitch on my wife's FX35 this summer after we got it. It does require cutting of the black part of the bumper for the vertical piece, but not near as much as what the stencil, in the kit, calls for. I modified it to hug the hitch and ony had to cut out a small area--used a dremel. It took about a full day and a half, but I am very particular. Oh, it also required removing the driver's side rear most fender cover, but it too can be modified to reinstall--instructions said to disguard. Anyway, let me know if you have any questions, I'll try to help.
