IPD 74mm Plenum for 991.1 Porsche 911 Turbo & Turbo S [91274]

IPD 74mm Plenum for 991.1 Porsche 911 Turbo & Turbo S [91274]

The remarkable 991 Porsche Turbo received a completely redesigned exterior, while the engine remained virtually unchanged from the previous 997.2 Turbo model. This Turbo is the most powerful, innovative, and capable Porsche Turbo to emerge from Stuttgart. The latest generation 9A1 engine delivers 520 horsepower (560 horsepower in the “S” version), once again setting a new standard in the sports car world. The 991 IPD Turbo Plenum closely resembles the 997.2 Turbo Plenums and is available in a single 74mm version that utilizes the factory 74mm throttle body. The 991 Turbo intake manifolds are smaller than those of the 997.1 Turbo, which improves boost response and fuel efficiency, though it limits the potential for substantial power gains. The 74mm throttle body provides sufficient airflow for these more restrictive intake runners, making a larger 82mm “Competition” version unnecessary.

Enhanced Power

• The already impressive power of the 991 Turbo can be further enhanced with the IPD Intake Plenum. The patented IPD Plenum design is highly effective for all forced induction applications, and the 991 Turbo is no exception. The power and torque gains delivered by the IPD Plenum are substantial, consistently outperforming the factory power curves from launch to redline. Maximum power increases occur in the midrange, where they are most needed and most impactful. The 991 Turbo Plenum provides smooth, linear power with significantly quicker boost response, extending the power band for a more enjoyable driving experience. Designed for both street and motorsport applications, the Turbo Plenums offer reliable performance, elevating the already thrilling Porsche Turbo experience.
