2014-2021 BMW M3/M4 V1 Style Carbon Fiber Diffuser | F80/F82/F83

*Please email us any special requests*

The back side of your F80 M3 and F82/F83 M4 deserves more than just the factory painted diffuser, especially once you’ve started adding carbon accents everywhere else. 

This V1-style Carbon Fiber Diffuser replaces the stock piece with a full carbon unit that frames the quad exhaust tips properly and gives your rear bumper real visual depth.

The 3-piece design includes the center diffuser and two side splitters, which together cover the entire lower rear bumper area in exposed carbon fiber. 

Made from real carbon fiber in a 2x2 weave pattern and finished in a glossy UV-protectant clear coat, this set holds up to exhaust heat, road grime, and weather exposure without the weave dulling or yellowing over time.

Installation uses a combination of bolts and 3M tape (both included) and professional installation is recommended for the best alignment across all three pieces. 

 Don't waste $800-$900 and save today with ours! This Diffuser will fit the 2014-2021 F80/F82/F83 BMW M3/M4.
