Do I need to remove the fog lamp to install this trim?

Not necessarily. The bezel frames around the lamp—test-fit first to confirm clearance. If your lamp sits proud of the bumper face, you may need to temporarily remove it for easier alignment.

Will this cover any existing bumper sensor holes?

This trim is designed for the fog lamp opening specifically. If sensors are positioned in that area, verify fitment before purchase—the bezel may not be compatible with active sensor brackets.

Does the chrome finish come pre-sealed, or will it need protection?

The finish ships ready to install. Over time, road salt and UV will dull the chrome—a periodic wax or chrome polish keeps it looking fresh, but it's not required for function.
