This part cross-references Walker Products Aftermarket 350-64026 for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough engine operation from incorrect air-fuel readings
• Elevated exhaust emissions from a failing upstream sensor
• Fault codes stored in the ECU for sensor-related issues

Installation Notes

Verify the upstream left or upstream right position before ordering. Inspect the sensor wiring harness and connector for damage during diagnosis, since physical wear can shorten sensor life and affect operation. Confirm thread size, connector style, and harness length against the original part before installation on your Land Rover LR3, Range Rover, or Range Rover Sport.
