Enhance the rear end of your F8X M3 or M4 with our 3-Piece V-Style Carbon diffuser. This is one of our most popular and aggressive options for the F8X. It includes three pieces, the diffuser and two side extensions.
We recommend using screws and 3M double sided tape to properly secure the diffuser to your vehicle and additional screws on each end of the diffuser to ensure proper fitment. Hardware and installation instructions are not included. We highly recommend professional installation, proper installation is critical to achieve the desired appearance with this diffuser. Once a part is modified or installed (including 3M tape), it is not eligible for return.
