Description
The IPD Competition 74mm Intake Plenum for the Porsche 986 Boxster Base 2.7L is a high-performance airflow upgrade designed to enhance the driving dynamics of Porsche’s iconic mid-engine roadster platform from 2000–2004. This application is engineered for enthusiasts seeking a noticeable improvement in performance without requiring additional engine modifications or ECU tuning.
The 986 Boxster Non-S 2.7L Plenum delivers strong and consistent performance gains across the entire power band, with the most noticeable improvements occurring in the mid-range RPM region where real-world driving enjoyment is most pronounced. The upgraded intake system improves airflow efficiency, increases intake velocity, and enhances overall engine responsiveness.
This setup is designed to work with the upgraded 74mm throttle body (up from the factory 68mm unit), allowing the engine to breathe more freely and produce improved horsepower and torque from launch through to redline.
The result is a more responsive, more engaging, and more enjoyable driving experience in both stock and lightly modified configurations.
The IPD 986 Boxster 2.7L Competition Plenum is widely regarded as one of the most effective bolt-on upgrades available for the platform, offering measurable gains without sacrificing drivability or reliability.
A custom IPD silicone intake hose is included with the plenum to ensure proper fitment and optimized airflow with the larger throttle body.
