Product Overview

Elevate the lower rear profile and visual aggression of your electric crossover with this pair of Fast Style Glossy Black Rear Bumper Add-On Diffusers. Custom-engineered for 2025-Present Tesla Model Y models, these rear valance add-ons add a performance-inspired aerodynamic profile directly into the factory lower bumper recesses.

Durable ABS Plastic Construction & Piano Black Finish: Molded from high-grade automotive ABS plastic, these diffuser add-on pods provide high impact strength, structural toughness, and long-term durability against road debris, gravel spray, and weather exposure. Coated in a deep, UV-protected high-gloss black finish that creates a sharp, high-contrast aesthetic against the matte factory lower valance.

Aerodynamic Dual-Fin Profiling: Each add-on piece features integrated twin vertical aero strakes designed to channel airflow and deliver a track-inspired rear appearance, giving the Model Y a wider, lower, and more defined stance without permanent body alterations.

Non-Invasive Tape-On Installation: Engineered using 3D vehicle scanning coordinates to mirror the exact curvature of the Model Y lower bumper pockets for a flush, gap-free fit. Mounts easily using the included heavy-duty automotive double-sided adhesive tape—no drilling or bumper removal required.

Installation

This Fast Style Rear Bumper Diffuser Add-On Insert Set is designed for a direct tape-on installation on compatible 2025-Present Tesla Model Y models.

Before installation, thoroughly clean and dry the factory rear bumper mounting areas. Remove any dirt, dust, grease, wax, ceramic coating residue, or other contaminants that could reduce adhesive strength.

Test-fit both diffuser inserts before removing the adhesive backing to confirm the correct driver-side and passenger-side positioning.

Apply the included heavy-duty automotive double-sided adhesive to the designated mounting surfaces if it is not already pre-applied. Carefully align each diffuser insert with the factory rear bumper recess and press firmly into position.

For best adhesive performance, installation should be performed on a clean, dry surface at a suitable ambient temperature. Avoid washing the vehicle or exposing the installed pieces to heavy moisture immediately after installation while the adhesive develops full bonding strength.

No drilling or bumper removal is normally required.

Installation manual is not included. Professional installation is recommended.
