Finish off your BMW G22 or G23 4-Series appearance with this Full Carbon Fiber Diffuser. This diffuser is crafted from genuine 2×2 weave full carbon fiber that will nicely match any other carbon fiber parts you have on your car from RW Carbon. The full carbon fiber is a stronger and better-looking weave. To ensure that this diffuser has a nice finish and does not fade we complete it with a thick, high-quality clear coat. Installation is 100% bolt-on, simply unbolt your factory diffuser and mount the new one using the same mounting points as OEM. Our carbon fiber G22/G23 4-Series diffuser is the perfect finish for the back end of the car. Choose RW Carbon for your 4-Series carbon fiber needs and receive a product you can be proud of to install on your vehicle.
