Competition Intake Plenum For Porsche 981 DFI Cayman/S/GTS (3.4L) (2014-2016) Models.

The IPD Competition Intake Plenum is the result of an extensive research and development program, engineered to deliver significant performance gains for your Porsche 981. This “Competition” version is designed to work with both the 3.4L “S” and 2.9L “non-S” applications, providing a powerful upgrade that replaces the factory 74mm throttle body with a larger 997 GT3 82mm throttle body.

This plenum takes advantage of the 981’s dual-intake design and features IPD’s unique internal dimpling effect. This technology, similar to a dimpled golf ball, controls the boundary layer of air and maximizes airflow, allowing for a more efficient and powerful combustion process. A custom silicone hose is included to perfectly fit the larger throttle body and further improve air flow.

Performance Gains:

The IPD Competition Plenum delivers impressive power gains that stay above the factory power curves throughout the entire rev range.

• 20 horsepower at the wheels

• 16 foot-pounds of torque at the wheels

The bulk of the power gains begin around 4000 rpm, continue all the way to redline, and are fully realized in the 6000 rpm range
