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.
