/ 01 · OVERVIEW

Create an aggressive, aftermarket look with our K-Style fully carbon diffuser for the F8X M3 and M4. This diffuser includes a functional F1-Style LED brake-light that will work seamlessly with your normal, OEM brake lights. We include the wiring harness necessary for the installation. The K-Style diffusers are made using our same genuine 2x2 carbon fiber fabric as our other M3 and M4 parts. Each piece is equipped with an OEM-like clear coat which protects against the harmful affects of UV rays and small rock chips. Every carbon fiber part we sell is quality checked and repackaged prior to shipping to ensure that you are receiving only the highest quality carbon fiber product. Due to the wiring required to install this diffuser, we strongly recommend professional installation. If you have any questions or concerns regarding this diffuser please reach out to us via the contact tab above.

These ship from our location in Los Angeles, CA. Shipping typically takes 3-5 days anywhere in the US.
