The IPD Plenums are a unique design that dramatically increases horsepower and torque by optimizing air flow efficiency. Air flow is managed through a diversion splitter that maximizes air speed into the engine. The charged intake air maintains a higher velocity by replacing the factory plastic "T" intake with a stronger and more efficient cast aluminum "Y" design.
This unique "Y" style plenum optimizes flow, improving acceleration and boost response. The new IPD replacement plenum eliminates the turbulent air flow by smoothly splitting and diverting the air flow and directing it towards the cylinders at a much higher air speed. This simple bolt-on plenum upgrade provides dyno proven increases in both power and torque throughout the entire rev range. A direct fit, no modifications required for fitment.
Gains: The 996 IPD Plenum provide power increases throughout the entire power band. Minimal gains of 11 to 12 hp are expected, with higher gains at mid range of 24-26 hp.
Made by IPD - Fits 2000-2004 911 Carrera models (996 generation).
