The Performance V1 air inlets will enhance the front end of your G8X M3 or M4. Dry carbon fiber was used in the production of the Performance V1 air inlets. A lighter, more better overall result is guaranteed when dry carbon is used instead of wet carbon. These air inlets also have a robust, UV-resistant clear finish on them. Both parts have a 2x2 carbon weave that closely resembles the OEM carbon fiber pattern used on the G8X generation. For proper installation, the front bumper must be removed. Installation by a professional is highly advised. All of our carbon fiber products come with a high quality fitting and finish guarantee.
