Description
The IPD 74mm Intake Plenum for the Porsche 987.1 Boxster S 2.7L / 3.2L is a direct bolt-on performance upgrade engineered to enhance airflow efficiency and engine performance across the entire power band. Porsche introduced the 987 S Boxster using a 3.2-liter engine derived from the previous 986 Boxster S platform, making it a naturally balanced but upgradeable performance platform.
This IPD Plenum version delivers strong and consistent power gains, with the most noticeable improvements occurring in the mid-range RPM region where driving engagement is most important. The upgraded airflow design improves engine breathing and enhances throttle response, creating a more responsive and more engaging driving experience.
This system is designed for Boxster S enthusiasts seeking meaningful performance improvements without sacrificing drivability or reliability. It delivers power gains throughout the entire rev range, making the vehicle feel more aggressive and more responsive in all driving conditions.
The IPD 74mm Plenum, combined with the upgraded 74mm throttle body (up from the factory 68mm), is widely regarded as one of the most effective naturally aspirated performance upgrades available for the 987.1 Boxster S platform.
It significantly improves the overall driving character of the vehicle and works exceptionally well alongside supporting modifications such as exhaust systems, ECU tuning, and other performance upgrades.
