Upgrade the rear profile of your BMW M340i with our G20 M340i LCI Competition-Style Rear Diffuser V1, designed specifically for the updated LCI M340i rear bumper.
The V1 design features a deep Competition-inspired centre section with four prominent vertical fins, framed by sharply sculpted outer sections that integrate around the factory M340i exhaust outlets. The angular upper detailing and pronounced centre profile give the rear bumper a lower, wider and more aggressive appearance while maintaining a clean, integrated look.
