Monitor exhaust oxygen concentration with the Walker 350-37025 LSU 4.9 Wideband Oxygen Sensor. Designed for high-performance and custom engine management applications, this sensor supports compatible standalone air-fuel ratio gauges, wideband controllers, OEM-pinned systems and performance ECUs.LSU 4.9 technology utilizes a planar zirconia dual-cell sensing element with an integrated heater to support wide-range lambda measurement. The sensor must be paired with a compatible LSU 4.9 controller or ECU input. LSU 4.9 and LSU 4.2 sensors feature different operating characteristics, connector configurations and controller requirements and are not interchangeable.A 970mm harness length provides adequate reach for custom routing and installation applications, while the exact OE fit connector and pin configuration support installation into compatible LSU 4.9 systems. Walker 350-37025 replaces Bosch 17025 and is engineered for applications requiring LSU 4.9 sensor technology. Always verify sensor technology, connector configuration, wiring and controller compatibility before installation.
