Enhance the rear end of your F87 M2 or M2C with the K1 diffuser. This diffuser features a 2x2 carbon weave and a 3rd brake lamp with an included wiring harness. The light wires up to your OEM tail lights and flashes on braking. Drilling is required, and professional installation is recommended.

For best/ideal fitment, we recommend removing the bumper for installation. We recommend lining up and drilling the edges first, and then working your way towards the middle of the diffuser. Once the diffuser is installed on the rear bumper, the rear bumper can be installed back onto the vehicle. Please note instructions are not included; but if you have any questions you are always welcome to send us an email.
