Original Rear Bumper Lower Spoiler

The Rear Bumper Lower Spoiler (also called a rear valance or diffuser) is an aerodynamic component mounted on the lower section of the rear bumper. Its primary function is to manage airflow underneath and around the rear of the vehicle, reducing turbulence and drag to improve efficiency and stability. Typically made from durable materials like ABS plastic, polyurethane, or carbon fiber, it also enhances the vehicle's sporty appearance. In Tesla models, this spoiler is precisely contoured to integrate with the bumper design while accommodating exhaust cutouts (on non-EV counterparts) or maintaining the clean aesthetic of electric vehicles.
