Product Details
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 a 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.
Use it as a stand-alone performance and styling piece, or build a complete package with other Unplugged Performance carbon aero. The diffuser extension matches perfectly with our Efficiency Spoiler for a well balanced rear setup. It also complements our front lips, side skirts, mirror caps, and additional carbon trim for a full vehicle theme that remains true to the Model 3 design language while delivering meaningful function.
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+ Tesla Model Y Long Range Rear Wheel Drive. If you want the look and the gains without compromising the car’s originality, this is the right way to do it. You get genuine aerodynamic benefits that you can feel on the highway and during spirited driving, a premium carbon finish that contrasts beautifully with factory paint, a reversible installation that keeps your options open, and seamless compatibility with the broader Unplugged Performance carbon lineup.

Will Tesla void my warranty if I install aftermarket parts?
A vehicle’s comprehensive warranty as a whole may not be voided due to use of aftermarket parts per the Magnusson-Moss Warranty Act (www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts). However, a manufacturer may require a customer to pay for parts and labor for a repair if there is direct causation between a customer’s alteration and the product or service repair being requested. It is in both manufacturer and customer’s interest to follow logic and reason so that the system of good faith is not abused. If this topic interests you please read the law as well as your warranty documentation. Ultimately we are Tesla owners and enthusiasts, we are not lawyers and cannot provide legal advice.
