This used OEM BMW X4 lower bumper valance/diffuser, part number 7338797, also replaces 7389890. Mounted at the rear, it covers the lower bumper area and helps manage airflow underneath the vehicle. Fits models with the 2.0L or 3.0L turbocharged gasoline engines. Over time, these diffusers can crack from debris or parking impacts, compromising the clean look and aerodynamic function.
