Moshammer Turbo Rear Diffuser for 997 Porsche 911 Turbo & Turbo S
Moshammer Turbo Rear Diffuser keeps a 997 Turbo current without dating it, a narrow line to walk on a car now firmly regarded as a modern classic. The engineering behind it is straightforward and honest: the diffuser works with the 997 Turbo’s smooth underbody to create a negative ground effect, the inverted wing profile that helps stabilize handling as speed rises. Visually it stays in OEM+ territory, adding definition below the bumper where the standard car is simply flat. Moshammer still produces it in Berlin to order, unpainted, with mounting material and a TUV parts certificate (§19.3). For an owner preserving a 997 rather than modifying it, that combination of restraint and documentation is the whole appeal.
Negative Ground Effect
- The 997 Turbo left the factory with a notably smooth underbody, and the Moshammer Turbo Rear Diffuser is designed to exploit it. Together they create a negative ground effect, the inverted wing profile that helps stabilize handling rather than simply looking purposeful. It is honest aerodynamics on a car that responds well to it.
Modern Classic Restraint
- A 997 Turbo is now valued for being what it is, so anything fitted to it has to respect the original design. Moshammer’s OEM+ approach adds structure and shadow below the bumper without introducing a modern styling language the car never had. Fitted well, it looks like a period-correct Porsche option.
Fitting and Finish
- The Moshammer Turbo Rear Diffuser is delivered unpainted with mounting material, so the finish can be specified to suit an original car. Installation uses the original screw points together with glue, and a TUV parts certificate (§19.3) is supplied with the part. Each one is made to order in Berlin.

Frequently Asked Questions
- Does the Moshammer Turbo Rear Diffuser fit a 997.2 Turbo? No. Moshammer lists it for 997.1 Turbo models only, which is the 2007 to 2009 car. The 997.2 Turbo and the 997 Turbo S, a 997.2 only model, fall outside the application. Send us your VIN if you want the specification confirmed before ordering.
- How does the Moshammer Turbo Rear Diffuser affect handling? Working with the smooth 997 Turbo underbody, the diffuser creates a negative ground effect that helps stabilize the car. It is a refinement rather than a race aerodynamic device.
- Will it look out of place on an original car? The Moshammer Turbo Rear Diffuser is developed as an OEM+ part, so the shape follows Porsche’s own language. On a well-kept 997 it reads as a factory option rather than a modification.
- What is supplied with the Moshammer Turbo Rear Diffuser? It arrives unpainted with the mounting material and a TUV parts certificate (§19.3).
- How is the Moshammer Turbo Rear Diffuser fitted? It installs at the original screw points with glue, and the mounting material is supplied. Professional fitting is recommended so the diffuser sits flush against the valance.
About Moshammer
Moshammer Automotive is a Berlin-based manufacturer of OEM+ aerodynamic refinement for Porsche, with a smaller line for Mini, Audi, BMW, and Mercedes-Benz. The house style is restraint with intent: parts drawn to look as though the factory had gone one step further, developed against original mounting points, TUV-documented where German road use demands it, and produced in small batches rather than stocked in volume. Their catalog spans single accents such as vent grills and wing end blades through complete Downforce and Tradition RS aero programs, alongside a range of multipiece forged wheels made to order in any size, width, and finish.
