Moshammer Thermodynamic Slats TDS for 997 Porsche 911 Turbo & Turbo S

Moshammer Thermodynamic Slats, TDS for short, are the detail that separates a 997 Turbo which looks quick from one that has been thought about. Their profile is not decorative: it governs how air moves between the air intakes and the intercooler sitting behind them, which on a forced induction car is the difference between charge air that stays cool and charge air that does not. Moshammer develops in Berlin to an OEM+ standard and supplies the TDS unpainted with mounting material and the correct adhesive, along with a TUV parts certificate (§19.3). For a car running a turbocharger upgrade or an enlarged intercooler, improving flow across that path is not a nicety, it is the whole reason to bother. Made to order in small batches, they read as factory to everyone who does not know what to look for.

Airflow and Cooling

The specific shape of the slats plays a real role in how well the 997 Turbo intercooler does its job, because it dictates the dynamic airflow between the intake openings and the cooler behind them. Air that arrives disorganised does less work, and on a turbocharged engine that inefficiency turns into heat you can feel in the way the car pulls. The TDS are designed to keep that flow moving usefully rather than tumbling, which is why Moshammer treats them as a must have on cars with upgraded turbochargers or larger intercoolers.

Design and Proportion

Viewed on the car the slats look like something Porsche might have specified, a fine louvred detail that adds visual depth without pulling attention away from the bodywork. That is the OEM+ discipline Moshammer works to: the part earns its place functionally first, and the aesthetic follows from the geometry rather than being imposed on it. Alongside the ram air scoops the effect is cohesive, a set of details that clearly belong to the same idea.

Installation and Finish

The TDS are an add on piece, so nothing factory is removed to fit them; they locate with the supplied mounting material and are secured with the special adhesive included in the box. They arrive unpainted, which leaves the choice of satin black, body colour or a contrast entirely open to you. A TUV parts certificate (§19.3) accompanies the part, which is unusual documentation for a component of this size and tells you how Moshammer approaches even the small pieces.

Frequently Asked Questions

What do the slats actually do? Their specific profile improves the dynamic airflow between the air intakes and the intercooler behind them, which helps the intercooler work as intended. On a 997 Turbo that path is directly connected to charge air temperature.
Do I need a turbocharger upgrade for these to be worthwhile? No, but that is where the benefit is most obvious. Moshammer describes them as a must have for turbocharger upgrades or enlarged intercoolers, where the demand for cool, well organised airflow is highest.
Are the ram air scoops required as well? They are not required, but the TDS were designed to improve the flow between the scoops and the intercooler, so the two work best as a set. The scoops are article P997.10.2025 and are sold separately.
How do they attach? They are an add on piece fitted with the supplied mounting material and secured with the special adhesive included in the box. No factory component is removed.
Do they come painted? No. They are delivered unpainted, which lets you match them to the car or run them as a deliberate contrast against the bodywork.

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.
