This part number, S20514, is listed for the Toyota 4Runner, Toyota Tacoma, and Toyota Tundra in the fitment data.

This part cross-references Hitachi Automotive ETB0187 for the same application.

Common Issues It Can Address

• Unstable idle caused by throttle body wear or contamination
• Delayed or inconsistent throttle response
• Airflow control problems in the intake system
• Driveability concerns related to a failing electronic throttle assembly
