Upgrade or replace your BMW Lambda Oxygen Sensor with this WEIDA Auto Parts unit, designed to fit popular BMW models including E46 325i/330i, E60 525i, X3, and E83. With part numbers 11787523434 and 11787523435, this sensor is built to integrate seamlessly with the M54 engine family, delivering accurate exhaust gas readings that feed your vehicle’s engine control system for optimal performance.
