Mercedes-Benz AMG C63 W205 | Prepreg Dry Carbon Fiber LED Rear Diffuser

Mercedes-Benz AMG C63 W205 (2014-2021) Prepreg Dry Carbon Fiber LED Rear Diffuser

Engineered for Mercedes-AMG C63 W205 (2014-2021) owners, this Prepreg Dry Carbon Fiber LED Rear Diffuser combines aggressive race aesthetics with an integrated LED brake/fog light. Imported from leading manufacturers around the world and quality-controlled by BYC Performance, this Mercedes C63 LED carbon rear diffuser bolts directly to OEM mounting points and wires easily to standard 12V circuits.

Unlike the standard non-LED diffuser, this version features an integrated F1-style red LED module in the center channel. The LED can be wired as a brake light, fog lamp, or position lamp, adding a distinct night-time signature to the rear. The IP67-rated waterproof module operates reliably in all weather conditions.
