Porsche 992.1 Carrera / S / GTS 3.0L
The new 992 Carrera engine is another modern marvel from Porsche. Although displacement remains unchanged at 3.0L, there are a plethora of upgrades that elevate this new 9A2 Evo engine head and shoulders above the previous 991.2 model engine. We were fortunate enough to have unlimited access to a 992 Carrera S during our extensive development and testing program. This unrestricted time frame proved to be invaluable, allowing IPD to scrutinize every engineering and design aspect in an effort to deliver the best performing Plenum possible.
Like all IPD Plenums, the 992 Plenum is a product of efficiency that produces substantial HP and TQ gains through a superior and patented "Y" design that manages and delivers optimized air flow for enhanced engine performance. The Plenum has been proven to delivered substantial net performance gains across both power bands and is guaranteed to elevate the driving experience of any Carrera.
Development started with a 1D simulation to optimize the treatment of pulse peaks in the intake tract using different pipe geometry and known engine parameters of the 992. We then graduated to optimizing 2D slices of the plenum in CFD, paying special attention to places where adverse pressure gradients that might cause separation. This allowed us to adjust curvatures on the plenum faces and build up our understanding of what was happening inside the pipe at full throttle.
After we were happy with the 2D slices we graduated to 3D adding in all the geometry to make this a plug and play bolt-on part with optimal performance characteristics. After hundreds of geometrical and CFD iterations, we were pleased with not-only the increase in mass flow compared to the stock intake, but also the uniformity of the charge pressure and velocity across the 2 branches.
The efficiencies of the Plenum dramatically reduce initial turbo lag down low helping access the power and torque sooner, but the bulk of the power and torque gains are realized from 4000 rpm to redline, where it is needed and enjoy most. The HP and TQ gains continuing to grow and out-perform the factory air distributor as you climb through the revs. Peak gains of 30+ wheel HP and 25+ wheel TQ are achieved at 6200 rpm.

Application Notes
Not for GT3 RS
Confirm the exact installation before selecting this part for any GT3 RS. Other Porsche installations may be suitable where an oversized 82mm IPD plenum is fitted; upgrade applications require a compatible competition plenum.
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The throttle body meters incoming engine air according to accelerator demand. Its internal butterfly opens or closes to vary the passage through the intake, working with the engine-management system to control airflow.
Functions
- Regulates air entering the intake manifold.
- Varies the intake opening as throttle demand changes.
- Provides the 82mm throttle connection required by a compatible intake installation.
Technical Details
- Brand: OE Match. Supplied reference: 99760511601.
- Throttle diameter: 82mm.
Symptoms of Fault
Possible reasons for inspection include an unstable or elevated idle, stalling, hesitation, sticking throttle movement, delayed response, throttle-position faults or reduced-power operation. Intake leaks and electrical connection problems can produce similar symptoms, so diagnosis should precede replacement.
Why Replacement Matters
Deposits, spindle wear or control faults can interfere with consistent airflow regulation. Replacement may be appropriate when testing confirms damage or malfunction that cleaning cannot resolve. Inspect adjoining seals, intake connections and wiring at the same time, and follow the vehicle-specific adaptation procedure where required.
FAQs
Can cleaning resolve the problem?
Cleaning may help when contamination is responsible. It will not repair worn mechanical parts or failed electrical components.
Will it fit every listed vehicle without other changes?
No. Some applications require a matching 82mm competition plenum. Check the existing intake arrangement and connection details.
Is adaptation needed after installation?
Some electronic throttle systems require a relearning procedure. Follow the instructions for the exact vehicle and engine.
