IPD Intake Plenum for Porsche 991.1 Carrera 4 / 4S

IPD Intake Plenum - Oxygen for the engine

Air or the oxygen it contains is an elementary component of every combustion engine. In principle, the higher the desired power output, the greater the quantity of oxygen required, which must be provided at the lowest possible temperature.

IPD Intake Plenum - Operating principle

The patented and revolutionary design of the IPD Intake Plenums for Porsche 991.1 Carrera 4 / 4S is based precisely on these adjusting screws which influence the performance of the engine.


The particularly flow-optimised IPD Intake Plenum made of high-quality, cast aluminium in Y-shape, replaces the standard air intake bridge made of plastic in T-shape.

The Y-shape enables a significantly faster air passage, while the special internal structure effectively prevents air vortices. Together, the IPD Intake Plenum supplies the engine with a significantly larger and cooler quantity of oxygen.

IPD Intake Plenum - Noticeably more power

The superior and extensively tested design of all IPD Intake Plenums noticeably increases engine power and torque over the entire speed range.

IPD Intake Plenums have earned a great reputation for being the most effective and cost-effective retrofit in the field of performance-enhancing engine components.

Each IPD Intake Plenum is measured and tested over countless hours on the dynamometer to ensure that each engine delivers the best possible power output. This enormous development effort, driven by IPD, results in a product of the highest quality and fitting accuracy - perfectly tuned for your Porsche 991.1 Carrera 4 / 4S!
