BMW G22 / G23 4 Series M-Sport Carbon Fiber Rear Diffuser
The 3DDesign Carbon Fiber Rear Diffuser is engineered specifically for the BMW 4 Series G22 Coupé and G23 Convertible M-Sport / M440i platforms, delivering an OEM-quality fit while enhancing the vehicle's rear stance with an aggressive, performance-inspired carbon look.
Manufactured by 3DDesign Japan, the diffuser is constructed from premium dry carbon fiber, providing exceptional structural strength, ultra-lightweight performance, and a sleek aerodynamic finish. Designed to integrate seamlessly with the factory rear bumper, it optimizes rear airflow characteristics while supporting dual/quad tailpipe setups (compatible with M440i OEM exhaust or 3DDesign 4-tailpipe exhaust systems).
Installation uses supplied mounting hardware and instructions. For models other than M440i, genuine OEM BMW adapter parts (5112 8075 842, 5117 8091 107) are required for installation.
