Transform the rear end of your BMW with the BMW G8X M3/M4 F1 Style Carbon Fiber Diffuser featuring a center LED light. This diffuser consists of a sharp F1-inspired design that frames the exhaust and gives the rear a whole new look. The piece is made from full carbon fiber and finished with a UV-resistant gloss clear coat for a deep, lasting shine. The integrated LED adds a modern motorsport look and can be wired to function as a brake/parking accent depending on your preference. The design complements OEM body lines for a bold upgrade that looks right at home on any G80 or G82/G83. This is especially the case since this F1 Style diffuser larger and appears thicker than our other center diffuser options because it eliminates the diffuser trim to become a larger solid singular piece.

Please note: This diffuser eliminates the OEM diffuser trim. You do NOT need to add our carbon fiber diffuser trim for a complete rear carbon look.

Installation

This BMW G8X M3/M4 F1 Style Carbon Fiber Diffuser installs using factory mounting locations and hardware. Test-fit the diffuser before final installation. Transfer any OEM clips as needed and secure the diffuser evenly across the bumper. The center LED requires basic wiring; most customers tap into the parking or brake light circuit for illumination. Professional installation is recommended for proper alignment and clean wiring.
