Rear Bumper Diffuser — Tesla OE 1135410-00-A / 1137819-00-A

Aftermarket, direct-fit rear bumper diffuser (rear fascia diffuser) for the Tesla Model 3 — the black lower diffuser panel below the rear bumper, non tow-hitch version. Cross-referenced to Tesla OE 1137819-00-A and 1135410-00-A. Being the lowest rear panel it is frequently scuffed or cracked by kerbs and low rear impacts, so it is a common standalone replacement and a replace-with item during rear bumper repair. Aftermarket replacement, locally stocked in Greater Vancouver.

Fits Tesla Model 3 (Jun 2017 – Dec 2023).
