Will this work if my bumper cover has sensor cutouts?

Yes, the reinforcement bar mounts behind the bumper cover, so sensor holes in your OEM cover won't affect fitment or function. The bar sits at the structural mounting level.

Does this require painting before installation?

The bar is aluminum and ships bare. If you want a finished look, paint it to match your bumper before bolting it down. Otherwise, it can go in unpainted and stay hidden behind your cover.

What tools do I need to install this?

Standard hand tools—sockets, wrenches, and a jack to access the underside. Work should take under an hour if you're familiar with bumper removal. Refer to your service manual for torque specs on the factory fastening points.
