Picked up one of RW Carbon's first ever F85 carbon fiber diffusers. Fitment was great and installation was simple. Best of all it held up perfectly through our harsh winters out here in Kansas. Between snow, ice and salt from the roads this piece still look like new.

RW Carbon diffuser quality is top notch. It's made out of 100% carbon fiber, no plastic reinforcement or fiber glass underneath like the other Chinese made brands. The fitment is very precise and the weave is perfect. I'm extremely happy with it on my X5M.
