Finish off your BMW G22 coupe or G23 convertible 4-Series with this Full Carbon Fiber Diffuser. This diffuser is crafted from 100% genuine dry carbon fiber that will nicely match any other carbon fiber parts you have on your car from RW Carbon. Our dry carbon fiber is stronger and lighter weight than other wet lay carbon fiber on the market. 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.
