So if you plan is to wow your fellow BMW drivers, then this diffuser is a must! The F8X M3/M4 GTX carbon fiber diffuser will seamlessly match other RW or OEM parts you have on the vehicle as we craft them from 2×2 carbon fiber. We know our customers care deeply about the parts they choose to install on their vehicle, which is why we only use the highest quality CF fabric, clearcoats and resin in the making of our products. Just like the rest of our product line, this GTX carbon fiber diffuser comes with the RW fitment and quality guarantee. Installation is purely bolt-on and does not require and special modifications or cutting.
