Designed as a replacement for the original center rear diffuser, this aggressive carbon fiber upgrade features pronounced shark-fin styling and a distinctive vertical LED brake light for a motorsport-inspired appearance.\u003c\/p\u003e\n\n\u003cp\u003eConstructed from 100% genuine full dry carbon fiber, the diffuser features a lightweight solid carbon fiber structure rather than a wet carbon fiber overlay or hydro-dipped plastic. Its premium 3K carbon fiber weave is protected by a hard UV-resistant clear coat on the visible exterior surface, while the hidden rear surface retains its natural raw carbon fiber finish. The sculpted vortex shark fins provide a bold, performance-oriented appearance.\u003c\/p\u003e\n\n\u003cp\u003eDesigned as a direct replacement for the factory center rear diffuser, this component uses compatible original mounting holes and a clip-on installation method. The integrated vertical LED brake light requires electrical wiring, including splicing and connecting to the appropriate vehicle circuit. The original diffuser must be removed before installation.
