Does not fit 2026 Tesla Model S Plaid with 2026 Refresh Front Fascia.

Improve both the aerodynamic performance and visual appearance of your Tesla with the addition of T Sportline's Carbon Fiber Rear Aero Diffuser.  Airflow under the Model S is directed to the diffuser's segmented laminar expansion chambers in effort to reduce turbulence and maximize downforce.   In addition to the subtle air management, the rear end of your Tesla will gain significant attractiveness.   

The diffuser is manufactured in a precision CNC'd alloy mold using pre-preg carbon fiber, which is cured in an autoclave.   The T Sportline diffuser attaches to factory mounting points. The T Sportline diffuser not only enhances the look of the car, but also provides a layer of protection against road debris, dings, and scratches.   No tools are necessary for installation.
