Will this bracket work with my factory license plate frame?

Yes—the bracket mounts the plate itself, and your factory or aftermarket frame slides over the plate after installation. Just make sure the frame isn't too thick or it may create gaps at the bumper.

Do I need fasteners besides what's on my car already?

The bracket uses the factory mounting points on the bumper beam. Confirm you have the OEM fasteners in place before mounting—if any are missing, grab replacements from a Honda dealer.

Will the bracket fit under the bumper cover, or does it stick out?

The bracket mounts to the beam behind the bumper cover and is designed to sit flush. Your license plate will be visible below the cover opening where it's meant to be.
