Description
The IPD Competition 74mm Intake Plenum is engineered for Porsche 996 Turbo enthusiasts seeking maximum airflow and performance from heavily modified turbocharged applications. Designed specifically for vehicles equipped with a larger 74mm Porsche throttle body, this high-flow intake plenum enhances airflow capacity, increases intake velocity, and supports the demands of high-horsepower builds exceeding 600 horsepower.
Built upon IPD’s proven intake technology, the Competition Plenum is optimized for vehicles equipped with upgraded turbochargers, larger intercoolers, high-flow intake components, performance exhaust systems, and aggressive ECU calibrations. By eliminating the airflow limitations of the factory air distributor, the IPD Competition Plenum allows the engine to breathe more efficiently at higher RPM levels, resulting in stronger top-end performance and improved power delivery throughout the rev range.
Whether installed on a serious street build, track-focused vehicle, or extreme horsepower project, the IPD Competition Plenum helps unlock the full potential of the legendary Mezger-powered 996 Turbo platform.

- Track-focused performance packages
Its larger internal volume and optimized airflow pathways allow the engine to maintain stronger power production at higher engine speeds where airflow demand is greatest.
74mm Throttle Body Compatibility
This Competition Plenum requires a larger 74mm Porsche throttle body, sold separately.
Benefits of the larger throttle body include:
- Increased airflow capacity
- Reduced intake restriction
- Improved throttle response under load
- Greater airflow efficiency at high RPM
- Better support for elevated boost levels
The combination of the 74mm throttle body and Competition Plenum creates a highly efficient intake system capable of supporting substantial power increases.
Enhanced Top-End Performance
One of the defining characteristics of the Competition 74mm Plenum is its ability to maintain power production deep into the rev range.
Benefits include:
- Stronger acceleration near redline
- Reduced power drop-off at higher RPM
- Improved airflow stability
- Enhanced engine efficiency under boost
- Greater usable power throughout the upper RPM range
For enthusiasts focused on maximizing track performance or achieving high horsepower targets, these improvements can significantly enhance overall vehicle performance.
