IPD Plenum 74mm For Porsche 997 Carrera Base 3.6L (2005-2008) Models.

The IPD Plenum for the Porsche 997 Carrera Non-S 3.6L delivers similar performance gains to the 3.8L Carrera S, with midrange horsepower increases of 24–26 and additional gains of 10–12 horsepower at higher RPMs. Its “Y” design improves airflow, creating a smoother, more linear power curve and enhanced throttle response for a more engaging driving experience.

Full performance is achieved once the factory DME completes its adaptation process, typically through a series of dyno pulls or full-throttle runs. Designed as a direct bolt-on replacement, installation is straightforward for mechanically inclined enthusiasts, though IPD recommends it be performed by a trained Porsche technician for optimal results and reliability.
