M Performance CFRP Rear Diffuser, Right - G90/G99 M5

This part is listed by BMW as BMW part number 51755B6E580 (51 75 5 B6E 580) and is described as the Right side of the rear diffuser for G90 M5 sedan and G99 M5 Touring wagon. The right side is sold separately.

This is the CFRP (Carbon Fiber Reinforced Plastic) version of the diffuser. It's also available in dry carbon fiber. CFRP will be slightly heavier overall.

BMW recommends using their carbon fiber/titanium exhaust tips for a better aesthetic appearance. Aftermarket exhaust may also work within the new framing of the diffuser.

Note: Comfort Access / “contact-less” tailgate operation will likely be disabled due to the carbon fiber blocking the sensor.

Not for cars with rear trailer hitch option (not available in the US).

This is a Genuine BMW G90 rear diffuser with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
