Show original supplier description
The 3D Design Rear Diffuser Set B is a premium carbon fiber exterior upgrade specifically designed for the BMW X5 G05 M Sport and M50i models. Its gloss clearcoat finish ensures a seamless integration with the vehicle's aesthetics, providing an OEM+ appearance. This diffuser is engineered to enhance the aerodynamic profile of the G05 X5, complementing the M-Sport bumper. It is designed for compatibility with both LCI and Pre-LCI versions of the BMW X5 G05 equipped with the M-Sport Package or M50i trim. Please note that installation of this diffuser may affect the functionality of the hands-free tailgate opening system. The product is manufactured in Japan with a focus on precision fitment and durability. Compatibility notes are crucial for this product: it is intended for the BMW X5 G05 CV30A, CV30S (xDrive 35d M SPORTS), JU44A, JU44S (M50i), JU8230A, and JU8230S (xDrive 35d M SPORTS) models, with specific production dates mentioned for some variants (e.g., 02/2019-02/2021, 02/2019~, 02/2021~). The seller notes that compatibility is based on maker data for JDM cars only and does not guarantee fitment, advising customers to conduct their own research. After-sale support does not extend to installation assistance.
