This part number, TB1138, is a direct-fit option for Porsche Cayenne and Porsche Panamera applications where the original equipment reference matches the listed interchange numbers.

What It Helps Solve

• Rough or unstable idle
• Delayed or inconsistent throttle response
• Throttle body fault codes related to electronic control
• Airflow restriction from carbon buildup or wear
• Driveability issues tied to a failing throttle body assembly

Installation Notes and Tips

Verify the OE part number and vehicle application before installation. Electronic throttle bodies often require throttle adaptation or relearn procedures after replacement, depending on the vehicle’s engine management system. Inspect the intake tract, connectors, and related sensors during service to confirm the root cause of the concern.
