This features a rare, matched Left and Right (LH/RH) pair of Genuine OEM BMW inner front kidney/headlight grille frame backing panel plates. Explicitly stamped with factory production casting marks 37 171 (Left/Links) and 37 172 (Right/Rechts), these structural ABS plastic composite frames are engineered natively for classic second-generation 3-Series platforms. Hand-labeled by a collector for verification, this specific set is optimized for the iconic 1988–1991 BMW M6 and related early-generation sport evolution layouts.

The inner backing trims mount directly behind the forward fascia grilles, acting as the structural partition borders that seal, support, and align the intake tract lines adjacent to the headlight buckets. Both items show a crisp factory-molded satin black textured finish with all rear structural mounting clips, guide notches, and isolation tab channels fully intact. Housed cleanly within their designated individual protective zippable storage transit bags, these New Old Stock (NOS) style replacement panels provide a simple, plug-and-play solution for high-level classic European concours restorations or front-end collisions.
