Do I need to remove the OEM grille or can I install this over it?

You'll need to remove the factory grille first. It bolts out from behind the bumper opening — pretty straightforward with basic hand tools. Once it's out, the new grille bolts directly into the same factory mounting holes.

Will I need any additional hardware or brackets?

The grille assembly itself is complete. Mounting hardware is not included — you'll reuse the fasteners from your OEM grille or grab standard hardware that matches the factory bolt pattern.

Does this need to be painted, or is it ready to install?

It ships with the matte black finish applied and ready to bolt on. If you want a custom color or prefer a different finish, plan for prep and paint before installation.
