986 Boxster S 3.2L Competition 74mm Plenum

The IPD 986 Boxster S 3.2L Competition 74mm Plenum is engineered to enhance the performance of your 2000-2004 Porsche Boxster S with the 3.2L engine. By utilizing a larger 74mm throttle body in conjunction with IPD's patented "Y" design plenum, this upgrade significantly improves airflow and intake air velocity. This performance modification is intended to provide noticeable gains throughout the power band, particularly in the midrange, delivering a more exhilarating driving experience. The system is designed for a direct fit and includes a custom silicone hose compatible with the larger 74mm throttle body. While installation is described as relatively straightforward, IPD strongly recommends that it be performed by a qualified Porsche technician. A 74mm throttle body is required for installation and may need to be purchased separately. Power gains are quoted at 15+ wheel horsepower and 15+ wheel torque, with improvements realized from launch to redline. This plenum upgrade is suitable for both stock and modified Boxsters, and no ECU modifications are necessary for installation and operation.
