Show original supplier description
The Genuine BMW 51748431653 is a left-hand brake air-inlet duct, originating from BMW's Motorsport division. This component was developed with competition and racing applications in mind, aiming to restore factory airflow and enhance brake cooling. As a dedicated motorsport part, the 51748431653 is designed for the BMW F82 M4 GT4. It is important to note that BMW Motorsport parts are typically released at the discretion of the Motorsport division, meaning availability can be limited, and delivery time estimates may vary. If this part is not in stock, contacting the seller is recommended for the most up-to-date delivery information. This air-inlet duct is sold individually. Installation may require modifications, as indicated by some sources noting that installation can require cutting into the front bumper. While this specific part is listed for the F82 M4 GT4, some sources suggest potential compatibility with F80 M3 and F82/F83 M4 models, though direct fitment verification through the sales team is advised due to the lack of explicit vehicle application data on some platforms.
