Give your F3X 4-Series a unique look with our brand new K Style diffuser for the F32 4-Series. The K Style is a popular diffuser option for the F30 3-Series; however, this is this first available K Style diffuser that is compatible with the F32 4-Series. This diffuser features a functioning third brake light that flashes when you brake by wiring up directly to your OEM tail lights. Additionally the light will stay on at night and illuminate further when the brake pedal is pressed. This piece also features the same 2x2 carbon weave that is found on our other F3X and F8X products. Each piece is quality checked extensively prior to shipping at our location in Los Angeles, CA. Please note that this part is not intended to be installed at home, professional installation is required. Additional self tapping screws near the tabs at the top of the diffuser are recommended for proper fitment.

DISCLAIMER

Please note that if you have the trunk assist option you will need to make some small cuts in the sensor bracket to allow clearance for the brake light. If you have any questions regarding installation please feel free to contact us at [email protected].
