BB991TurboRD3 Porsche 991 Turbo Rear Diffuser

Give your Porsche 991 Turbo a more aggressive and performance-driven appearance with our rear diffuser, designed specifically for 2012–2015 models. This upgrade transforms the rear profile of your car, adding race-inspired styling while enhancing airflow efficiency underneath the bumper.

Crafted for a precise, flush fit, the diffuser integrates seamlessly with the factory rear bumper—no gaps, no awkward lines—just a clean, professional finish that looks right at home on the 991 Turbo.

Beyond the visual upgrade, the diffuser improves aerodynamic balance by managing turbulent air at the rear of the car, helping with stability at speed and reducing drag.

Installation is simple and straightforward, making this an easy weekend project. Molded from our proprietary polyurethane formula, it’s built to last — virtually indestructible under real-world driving conditions, resistant to cracks, chips, and road abuse.

Aggressive styling, functional performance, and unmatched durability — the perfect rear-end upgrade for your 991 Turbo.
