IPD 74MM PLENUM FOR 996 PORSCHE 911 CARRERA [96174-3.4]
IPD 74mm Plenum for 996 Porsche 911 Carrera [96174-3.4]
The IPD 74mm Plenum for the 996 Porsche 911 Carrera 3.4L offers a substantial performance boost for the naturally aspirated engine, where finding power gains is notoriously difficult. This straightforward bolt-on upgrade replaces the factory plastic air distributor with IPD’s patented aluminum “Y” style Plenum, providing impressive horsepower gains of 25 and torque increases of 22 through a more efficient design. These improvements are most notable in the mid-range, where power is needed and appreciated, though benefits extend across the entire RPM range. The enhanced mid-range power creates a smoother, more linear power curve, reducing the typical dip found in the factory setup and significantly enhancing overall performance. This transformation in power delivery promises to elevate the Porsche driving experience for Carrera enthusiasts.
