BMW OEM rear bumper valance / diffuser (part 7986161, also replaces 8058758) — a used genuine piece removed from a donor vehicle. This rear diffuser fits M3 and M4 models with the 3.0L turbocharged I6 engine. It shapes airflow under the bumper and gives the rear a more aggressive appearance. The "m" designation indicates it's the M-specific style.
