Do I need to remove the bumper cover to install this?

Yes. The reinforcement bar bolts underneath, so you'll need to pull the bumper cover off to access the mounting points. It's a straightforward job with basic tools.

Will this work if my bumper has sensor holes for parking assist?

This reinforcement bar is designed around factory attachment points and should not interfere with existing sensor cutouts. That said, test-fit before final assembly to confirm clearance in your specific setup.

What condition does it ship in—does it need painting?

The bar arrives unpainted hard panel. If you want it color-matched to your bumper, prep and paint it before installation. If you're leaving the bumper cover on, the reinforcement stays hidden.
