Does this grille bolt straight to my existing bumper cover?

Yes. It fastens at the factory mounting points already present on the bumper — no drilling, no adapter brackets needed. Installation uses basic hand tools only.

Will I need to paint or prep this before installing?

No. The grille ships in finished black and is ready to bolt on. If you want to match a different bumper color, you'll handle that as a secondary step after installation.

Does the grille come with mounting hardware?

Hardware is not confirmed with this assembly. Test-fit first — most installs use the factory fastener holes already in your bumper, but verify your hardware situation before committing.
