Will this work with my factory sensors or fog light cutouts?

Test-fit before committing to final installation. If your bumper has existing openings, confirm the lip doesn't obstruct them during the dry-fit phase.

Do I need to paint this before installing it?

It ships matte black and ready to bolt on. Paint it before installation if you want a different finish, or install as-is if matte works for your build.

What fasteners do I need to mount this?

The lip uses factory mounting points, but the specific bolt size and quantity aren't confirmed in the listing. Grab your service manual or test-fit to see exactly what you're working with.
