This new Kholen Style carbon fiber rear diffuser is the perfect piece to add that race inspired feel to your BMW F80 M3 or F82 F83 M4. This diffuser comes with a real working LED 3rd brake light that will work with your brake lights. A wiring harness and install guide will be included with every diffuser. The Kholen style diffusers are made using our same genuine 2×2 carbon fiber fabric as our other M3/M4 parts. Each piece is clear coated for that brilliant shine and to help protect it from harsh road conditions. Each piece is then quality checked prior to shipping worldwide. So rest assured when purchasing your Kholen style diffuser that you will receive a top quality product. If you have any questions, please contact us today!

Installation

The diffuser itself is fairly simple to install. It replaces the OEM F8x M3/M4 plastic diffuser and re-uses OEM mounting location and requires self tapping screws for the sides. We do recommend professional installation in order to wire the harness for the 3rd brake light. You will need to tap into the taillights wiring harness. For a wiring diagram, please contact us.
