Show original supplier description
The BMW Genuine Parts 51125A7F3C5 is an M Performance rear center diffuser crafted to enhance the aesthetic and aerodynamic profile of compatible BMW 5 Series models. This genuine BMW part is designed to integrate seamlessly with the vehicle's existing M Sport exterior, specifically those equipped with the "09T1 M SPORT EXTERIEURUMFAENGE" special equipment. Installation of this rear diffuser necessitates a precise process and the use of several supplementary components. These include BMW's proprietary adhesive primer VP 206 (30ML), cleaning solution Betaclean 3350 (100ml), and bonding agent Betafill 217 (300ml) for secure adhesion. Additionally, an expanding rivet (51 48 1938725) and a fillister head screw (TS5x20, 07 14 6986938) are required for proper mounting. The center diffuser must also be installed in conjunction with the M Performance rear diffuser left (51 12 5A7F3C0) and M Performance rear diffuser right (51 12 5A7F3C3) to complete the assembly. This M Performance rear center diffuser is compatible with the BMW 5 Series G60 (Saloon) and G61 (Touring) chassis. Specific models include various 520d, 520dX, 520i, 523d, 523dX, 530e, 530eX, 530i, 530iX, 540dX, 550eX, i5 eDrive40, i5 M60 xDrive, and i5 xDrive40 variants. It is recommended to verify exact fitment with your specific vehicle's VIN, as compatibility can vary by trim and engine configuration.
