Will this bumper cover work with my vehicle's factory fog light openings?

The M4 Look design features its own intake proportions. Verify that your existing fog light housings align with the cover's cutout locations before installation. If modifications are needed, plan to work from inside the bumper once mounted.

Do I need to remove the lower valance, or does this cover over it?

This bumper cover is designed as a direct replacement for the front fascia. Reference your vehicle's service manual to confirm whether the lower valance stays in place or requires removal for clearance during installation.

What surface prep should I do before painting?

Sand the surface with appropriate grit, clean away all dust and debris, and apply your chosen primer and topcoat system according to the paint manufacturer's specifications. Proper prep ensures adhesion and finish quality.
