IPD Plenum 3.8L 74mm For Porsche 991 Turbo Base/S/GT2RS (2017-2018) Models.

The IPD Plenum and Y-Pipe upgrade for the Porsche 991.2 Turbo is designed to maximize the performance potential of an already exceptional platform. While Porsche introduced numerous enhancements to the 991.2 Turbo, including improved intake ports, larger injectors, upgraded fuel delivery components, larger turbo compressor wheels, and more efficient intercoolers, the factory intake system remained largely unchanged. This allowed IPD to develop a performance-focused intake solution that integrates seamlessly with the vehicle while significantly improving airflow efficiency.

Engineered to deliver substantial horsepower and torque gains across the entire power band, the IPD Plenum upgrade provides its most dramatic improvements in the midrange, where acceleration and responsiveness are most noticeable. Power gains are especially strong between 3,500 and 5,000 RPM, with peak increases exceeding 45 wheel horsepower and more than 60 wheel torque. The result is sharper throttle response, stronger acceleration, and a more engaging driving experience that further enhances the capabilities of the Porsche 991.2 Turbo.
