Its location on the rear of the vehicle makes it easy for technicians to identify the correct mounting area and reduces labor time when replacing a damaged component.

Application in repairs and upgrades

The lower rear bumper diffuser cover is suitable for both standard replacement of a damaged panel and comprehensive refreshing of the rear bodywork.
