986 Boxster S 3.2L Competition Plenum

The IPD 986 Boxster S 3.2L Competition Plenum is a performance-enhancing modification for the Porsche 986 Boxster, specifically models from 2000-2004 equipped with a 3.2L engine and utilizing a 74mm throttle body. This plenum replaces the restrictive factory "T" style air distributor with IPD's patented "Y" design. This improved design promotes better airflow and increased intake air velocity, which is crucial for maximizing engine output. The product is specifically designed to integrate with a larger 74mm Porsche throttle body (sold separately), further enhancing the intake system's efficiency. Installation of the IPD Plenum is described as relatively straightforward, though a qualified Porsche technician is strongly recommended for the procedure. The plenum comes complete with a custom silicone hose designed to fit the 74mm throttle body and all necessary additional hardware for installation. No ECU modifications are necessary for this upgrade. The IPD Plenum is engineered to deliver significant performance gains, with the manufacturer claiming 15+ wheel horsepower and 15+ wheel torque. These gains are realized across the entire power band, from launch to redline, with a particular emphasis on midrange improvements where drivers often seek enhanced response. This upgrade is suitable for both stock and modified Boxsters.
