Enhanced Airflow and Throttle Response. This 87 mm Powr-Flo throttle body replaces the factory unit to boost airflow into the 6.6 L gas engine, improving low-end torque and throttle responsiveness under load.
Precision Construction. Machined from billet aluminum and anodized for corrosion resistance, the throttle body ensures smooth operation and long-term reliability. The integrated sensor port accepts the OEM throttle position sensor for seamless ECU integration.
Installation. This product installs by unbolting the factory throttle body, swapping the unit and sensor, and following the provided calibration procedure—no modifications to intake plumbing are required.
