The specifically designed 991.1 Carrera S 3.8L Plenum is a direct bolt-on upgrade that replaces the factory air intake distributor and utilizes all pre-existing factory hardware and 82mm throttle body.

The improved IPD intake design allows for smoother, less turbulent and more efficient air flow resulting in impressive power and torque gains for Porsche driving enthusiasts.

The superior design of the IPD Plenum provides an additional 15 horsepower at the wheels. Unlike previous naturally aspirated IPD Plenums that delivered stronger gains in the mid range, the IPD Plenums deliver a similar shaped power curve as the factory but are considerably stronger from the mid range to redline without any loses in power down low.

Performance gains remain at 15+ horsepower and 14+ foot pounds at the wheels. As with most IPD Plenums, the bulk of the power gains are realized in the mid-range where they are most used and enjoyed. Unlike other mods, the IPD Plenums deliver net power gains across the entire rev range.
