What this part does
The fender liner mounts inside the wheel well, creating a contoured physical barrier between the tire tread and the internal cavity of the chassis. It shields the engine bay, headlight wiring harnesses, fog light connectors, and suspension pivot points from water, road salt, mud, and high-velocity debris thrown up by the rolling tire. Beyond physical protection, the panel is precisely shaped to route airflow for brake cooling and aerodynamic efficiency, while also utilizing material properties to isolate road and tire noise from the passenger cabin. When a splash shield is torn, cracked, or completely missing, critical electrical modules and structural metals are left highly vulnerable to accelerated corrosion and direct impact damage.

Before you order
Verify the 11-digit part number stamped directly on the back of your original inner fender before purchasing. The BMW 7 Series utilizes multiple liner variations for the front and rear sections of the wheel well, and fitment changes depending on whether the vehicle features the M Aerodynamics package, auxiliary cooling radiators, or specific staggered wheel dimensions.
This panel is molded to attach securely to the lower bumper cover, the metal chassis rail, and the adjacent belly pans. You must ensure the mounting tabs on your adjoining body panels are completely intact, as a failure or break in one underbody shield often transfers stress and allows wind to catch the others.
Mounting fasteners, including the 8mm hex-head screws, blind plastic rivets, and expanding metal nuts, are not included with this replacement. Because these specific hardware pieces become brittle from constant thermal cycling and harsh road exposure, carefully extracting and retaining them from your existing setup is required for proper installation.
