Rear diffuser for BMW G30 5 Series models, made of gloss black ABS or polypropylene (PP) plastic. It gives a sportier, race-car rear look and is an affordable alternative to carbon diffusers.
Pre-order: this product is made to order, with an expected delivery time of more than 30 days.
Available styles
- CS Style with brake light – one-piece gloss black ABS diffuser with two exhaust cutouts on each side, red reflectors at both ends and a triangular F1-style LED brake light in the center, which also improves visibility.
- Polypropylene diffuser with exhaust trims (B58, M Sport) – polypropylene (PP) part replacing the factory diffuser, with vertical center fins and one exhaust opening on each side, plus a 4-piece chrome exhaust tip trim set for a quad-pipe look.
The diffusers are not made of carbon.
Compatibility
BMW G30 5 Series sedan. The CS Style with brake light version is made for the 2017–2023 G30; since the exhaust openings differ by engine and the rear bumper type also matters, please check with us about your car's engine and bumper before ordering. The polypropylene diffuser is made for the B58-engined BMW G30 with the M Sport package (2018–2023); if you have questions about model year fitment, please check with us. Neither version is suitable for the BMW F90 M5.
Package contents
CS Style: 1 diffuser with the necessary mounting hardware. Polypropylene diffuser: 1 diffuser, 4-piece exhaust tip trim set and the necessary screws.
Installation
The diffuser replaces the factory part. Because of the precise fitting and the wiring of the CS Style brake light, professional installation is recommended. For the additional brake light, check the applicable regulations before road use. If you have any questions, feel free to contact us!
