Will this bumper work with my factory fog light cutouts and parking sensor holes?

This is an AMG-style cover, so the intake and air dam layout differs from the base bumper. Before purchase, compare the fog light opening size and sensor hole positions on the product images to your current bumper. You may need to drill or modify cutouts to match your vehicle's lighting and sensor setup.

What should I do to prep this for paint?

Sand and prep the surface with standard automotive sandpaper before applying your chosen primer and topcoat. Clean off any dust or release agent residue, and follow your paint supplier's surface prep guidelines for best adhesion and finish.

Does this bumper cover fit over the lower valance or replace it?

This is a bumper cover assembly. It will mount to your existing bumper beam and mounting points. Depending on your lower valance design, you may need to adjust or remove trim pieces for clean fitment. Compare the AMG styling lines in the product images to your current setup to confirm clearance.
