Begin or finish off your carbon fiber journey of your BMW G80 M3 or G82/G83 M4’s appearance with this Performance Style Carbon Fiber Diffuser. This diffuser is crafted from genuine 2×2 carbon fiber that will nicely match any other carbon fiber parts you already or will have on your car from RW Carbon. To ensure that the diffuser has a lasting shine and shimmer we finish off each piece with a thick and high quality clear coat. Installation is 100% bolt on, simply unbolt your factory diffuser and mount ours using the same mounting points as the OEM diffuser. Our carbon fiber BMW G8X M3/M4 diffuser will fit 2021+ BMW G8X M3/M4 applications but only those with the performance exhaust option from BMW. Choose RW Carbon for your M3/M4 carbon fiber needs and receive a product you can be proud to install on your vehicle that will be sure to turn heads along the road.
