Begin your BMW i4's carbon fiber journey with this Carbon Fiber Diffuser. This diffuser is hand crafted from genuine dry carbon fiber that will perfectly match any other carbon fiber parts you have on your car from RW Carbon. Our dry carbon fiber is a stronger and lighter than regular CF so enjoy the weight savings while getting a far more durable product. To ensure that this diffuser has a nice finish and does not fade or chip we complete it with a thick and high-quality clear coat. Installation is 100% bolt-on by simply unbolting your factory diffuser and mounting the new one using the same mounting points as OEM. Our carbon fiber i4 diffuser is just the right piece to bring your rear up to new standards. Choose RW Carbon for your i4 M50 carbon fiber needs and receive a product you can rock for years.
