Akrapovic DI-BM/CA/9/G 2021+ BMW M3 (G80)/M4 (G82) Rear Carbon Fiber Diffuser - High Gloss

This Akrapovic rear carbon fiber diffuser delivers precise aerodynamic enhancement for 2021+ BMW M3 G80 and M4 G82 models.

  • Finish – High gloss clear coat for showroom-ready appearance and UV protection
  • Aerodynamics – Directs exhaust gases and underbody airflow to generate downforce and stability
  • Fitment – Bolt-on installation with no modifications required for Base, Competition, xDrive, CS, and CSL variants
  • Durability – Motorsport-grade quality withstands track abuse and daily driving
