Unlock real aero performance and a sharper OEM+ look with the Carbon Diffuser Rear Trim Extension for the Tesla Model 3 Performance (2024+). This upgrade lengthens the factory diffuser and adds two central strakes that guide airflow more effectively through the rear tunnel. The result is a rear end that looks more purposeful and delivers measurable gains in stability and efficiency, all while preserving a factory-level fit and finish.

This part was developed and validated with CFD to ensure it is more than an aesthetic piece. In simulation, the diffuser extension used with our Efficiency Spoiler reduced drag by approximately 40 N, about 2.4 percent, while improving net downforce by about 534 N. In plain terms, the car slices the air a little cleaner and feels more planted at speed. The longer diffuser increases the working surface area where pressure is lowest, which adds rear grip, and it encourages a smoother transition as air exits into the wake, which is how a diffuser trims drag. The added strakes also help delay flow separation so the air stays attached farther back, supporting both stability and efficiency.

Built in premium carbon fiber, the extension delivers the crisp weave and deep finish enthusiasts expect, with the durability needed for daily use. Against factory paint and trim, the carbon surface creates a high-contrast visual that instantly elevates the rear of the car. Pair it with other carbon accents for a cohesive motorsport look, or run it as a single upgrade for a clean, purposeful change that reads as factory plus.

Installation is clean and reversible. No permanent modifications or disassembly are required. The extension is designed to integrate with the existing diffuser location, so you can return the car to stock at any time. This makes it a smart choice for leased vehicles or owners who want upgrades that respect the integrity of the chassis.

Fitment is focused and precise. This Carbon Diffuser Extension and Trim is intended for the 2024+ Model 3 Performance, 2024+ Model 3 Long Range AWD, and 2024+ Model 3 Long Range Rear Wheel Drive.
