Description
The IPD 82mm Intake Plenum for the Porsche 997.2 Carrera S was engineered specifically for Porsche’s advanced 3.8L Direct Fuel Injection (DFI) engine. Designed as a direct bolt-on replacement for the factory air distributor, this innovative intake upgrade enhances airflow efficiency, increases intake velocity, and delivers measurable performance gains without sacrificing reliability, drivability, or everyday usability.
Porsche’s DFI engine platform introduced a completely redesigned intake system focused on improving fuel efficiency, emissions, and combustion efficiency through precise fuel delivery directly into the combustion chamber. While this sophisticated design created a highly refined performance package, it also made extracting additional horsepower considerably more challenging.
Leveraging its patented intake technology, IPD developed a revolutionary plenum design that overcomes these engineering challenges. Featuring IPD’s patented “Y” configuration and an enlarged plenum chamber, the system promotes smoother airflow, reduced turbulence, and increased air velocity throughout the intake tract. The result is improved engine breathing and increased power output across the usable RPM range.
Unlike many aftermarket intake upgrades that focus solely on peak horsepower, the IPD DFI Plenum maintains the factory power curve characteristics while significantly strengthening performance from the mid-range through redline. Dyno testing has demonstrated gains of up to 15 horsepower at the wheels, providing stronger acceleration and enhanced driving dynamics without sacrificing low-end torque.
Designed specifically for the 997.2 Carrera S 3.8L engine, the plenum retains the factory 82mm throttle body and utilizes existing factory mounting points and hardware for straightforward installation.

Advanced DFI Intake Design
The IPD DFI Plenum incorporates two key engineering improvements:
Patented Y-Flow Configuration
IPD’s patented Y-shaped intake design improves airflow distribution throughout the intake system, allowing air to reach the cylinders more efficiently and evenly.
Enlarged Plenum Volume
The larger plenum chamber helps stabilize airflow while reducing turbulence, increasing intake air velocity and improving combustion efficiency across the engine's operating range.
Together, these enhancements allow the DFI engine to breathe more efficiently and generate additional power without requiring extensive modifications.
Installation
The IPD 997.2 Carrera S DFI Plenum is designed as a direct bolt-on upgrade and utilizes:
