Upgrade your G30 with the AUTRAGO M Competition Style Rear Diffuser, designed compatible with 2017–2023 BMW G30, G31, and G38 models equipped with the M Sport rear bumper. This diffuser draws inspiration from the M5 Competition design, delivering an enhanced, motorsport-inspired look to your rear end. The bold, aerodynamic styling not only amplifies your vehicle's performance aesthetics but also reflects the refined engineering typical of BMW's M line. Crafted from premium ABS, the diffuser combines lightweight flexibility with durable strength, ensuring a perfect balance between style and functionality. The pre-painted gloss black finish adds an elegant touch that complements the car's factory body lines. Installation is straightforward for professionals—simply remove the stock diffuser and clip on the new one. For M550i models, note that rectangular exhaust tips are not compatible; a round exhaust tip conversion is required. No manual included. Professional installation is strongly recommended to ensure perfect alignment and secure fitting.
