Performance Design LT2 C8 Corvette Carbon pTR Intake Manifold
Description
Performance Design LT2 C8 Corvette Carbon pTR Intake Manifold
Maximum Airflow for Serious C8 Performance
The Performance Design Carbon pTR Intake Manifold is a high-flow intake upgrade engineered specifically for 2020+ C8 LT2 Corvette coupe applications. Built around the airflow and packaging demands of the mid-engine LT2 platform, this system combines a carbon fiber upper plenum with a glass-reinforced composite lower manifold to improve airflow capability while maintaining factory-style integration.
For C8 owners looking to move beyond the limitations of the factory LT2 intake, the Carbon pTR system delivers increased plenum volume and airflow efficiency. Performance Design reports gains of approximately 25 rear-wheel horsepower when used with a 95mm throttle body. Actual results will vary depending on the complete vehicle combination.

Performance Notes
*Intake manifold gains are dependent on the total vehicle setup, including throttle body size, exhaust configuration, and calibration strategy. The commonly referenced gain for this intake is approximately 25 rear-wheel horsepower with a 95mm throttle body, but actual results will vary.
Stock vs Carbon pTR Intake Manifold
The factory LT2 intake manifold is designed around packaging constraints and broad OEM requirements. The Carbon pTR intake increases plenum volume and airflow capability, making it better suited for higher-performance naturally aspirated combinations and future upgraded builds. When paired correctly with the right throttle body and supporting components, it provides a measurable airflow advantage over the stock system.
