Moshammer Turbo Rear Diffuser for 991.1 Porsche 911 Turbo & Turbo S

Moshammer Turbo Rear Diffuser goes after the two things that matter most at the back of a 991 Turbo: stability and heat. The vented frame and its mesh grills draw hot air away from the exhaust so cooling moves closer to what Porsche’s GT models enjoy, while the diffuser surface maximises downforce and airflow efficiency where the underbody ends. Moshammer engineered it in Berlin as an OEM+ component, so one of the fastest cars Porsche sells gains function without gaining drama. It is delivered unpainted with mounting material and a TUV parts certificate (§19.3). For an owner who genuinely uses the performance, the argument for fitting it was never really cosmetic.

Downforce and Stability

Moshammer developed this diffuser to maximise downforce and airflow efficiency at the rear, and the benefit shows itself where a 991 Turbo spends its best moments, at high speed on a good road. Improving how air leaves the underbody improves overall stability rather than any single number on a spec sheet. It is the sort of gain an owner feels in the steering long before thinking about the part that caused it.

Hot Air Extraction

The vented frame with mesh grills is the technical heart of the design, simplifying the removal of hot air from the engine and exhaust area. Porsche uses the same thinking on its high-performance GT models, where exhaust cooling is treated as a design requirement rather than an afterthought. On a turbocharged car, that attention is more than decoration.

Unpainted and Certified

The article is delivered unpainted with its mounting material, ready for the finish you specify. A TUV parts certificate (§19.3) accompanies it, which matters for German registration and speaks to how the part was developed. Production happens in Berlin once the order is placed.

Frequently Asked Questions

What does the venting do on a Turbo? It simplifies the removal of hot air from the engine and exhaust area, which optimises exhaust system cooling in the way Porsche approaches it on the GT models.
Does it increase downforce? Moshammer developed the diffuser to maximise downforce and airflow efficiency at the rear, which improves overall stability at high speeds. No figures are quoted for the part.
Are the mesh grills part of the delivery? Yes. The vented frame is supplied with its mesh grills and the mounting material.
Does it fit both Turbo and Turbo S? Yes, all 991.1 Turbo and Turbo S models are covered.
Will it need painting? It arrives unpainted, so the finish is chosen by you and applied before installation.

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.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
