This used OEM BMW rear bumper valance/diffuser, part number 3414396, was removed from a donor vehicle. Also known as a rear diffuser, it mounts on the lower portion of the bumper to finish the rear appearance and aid underbody airflow. It fits BMW X3 models equipped with either the 2.5L or 3.0L naturally aspirated inline-six engine. Over time, these valances can develop cracks or lose their mounting clips, making a clean, undamaged replacement a practical fix.
