IPD Plenum 3.8L 74mm For Porsche 991 Turbo Base/S (2013-2016) Models.

The IPD Intake Plenum for the Porsche 991 Turbo is designed to enhance airflow efficiency and unlock additional performance from the already powerful twin-turbocharged platform. Utilizing IPD’s patented plenum design and retaining compatibility with the factory 74mm throttle body, this upgrade improves air distribution and boost response, helping the engine produce stronger and more consistent power throughout the RPM range.

Engineered specifically for the 991 Turbo, the plenum delivers noticeable gains in both horsepower and torque while maintaining smooth, linear power delivery. Performance improvements are especially evident in the midrange, where enhanced throttle response and quicker boost buildup contribute to stronger acceleration and a broader, more usable power band. Suitable for both street-driven and performance-oriented vehicles, the IPD Plenum is a proven upgrade that elevates the driving experience while preserving the reliability and refinement expected from the Porsche Turbo platform.
