This Bosch LSU4.2 O2 Sensor Extension Harness provides a 4-foot (48-inch) extension for LSU4.2 wideband O2 sensor wiring and is designed to fit Bosch WBO2 wideband O2 sensors. It enables longer sensor installation paths in automotive applications where the sensor needs to be positioned farther from the engine or controller, while maintaining compatibility with LSU4.2 and Bosch WBO2 systems.
