IPD Competition Plenum 82mm For Porsche 996 Carrera S 3.6L/Base 3.4L (2000-2004) Models.

The IPD Competition Plenum for the Porsche 996 Carrera is engineered to unlock the full performance potential of the water-cooled 911 engine, replacing the factory “T”-style air distributor with IPD’s patented “Y” design. This advanced design improves airflow distribution to both cylinder banks, reduces turbulence, and increases intake air velocity, delivering substantial gains in horsepower and torque across the entire RPM range.

Optimized for use with larger throttle bodies, the Competition Plenum upgrades the factory 74mm throttle body to the 82mm Porsche 997 GT3 throttle body, enhancing airflow and further boosting power and throttle response. When paired with high-performance exhaust systems, the plenum provides balanced engine breathing, resulting in smoother, more linear power delivery and stronger midrange and top-end performance.

Available with two silicone hose options, the IPD Competition Plenum fits either the factory air box or popular aftermarket intake systems, making it ideal for moderately to heavily modified 996 Carreras. Full performance is realized once the factory ECU/DME completes its adaptation process, typically achieved through spirited driving or dyno pulls. This upgrade delivers noticeable and impressive power gains that elevate the driving experience for Porsche enthusiasts seeking maximum performance.
