Walker 250-24713 Oxygen Sensor

Walker Products OE Oxygen Sensor for BMW

Walker Products OE 250-24713 is a heated oxygen sensor built as an OE-style replacement for specific BMW applications. It is designed for downstream positions and provides the ECU with the feedback needed to monitor exhaust performance and emissions control.

For BMW 650i, X5, X6, 750i, and related models, this oxygen sensor is a direct-fit solution for the listed bank and sensor locations. The Walker Products OE line focuses on application-specific fitment, connector style, and signal output so the replacement matches the vehicle’s original sensor requirements.

• Part number 250-24713
• Heated oxygen sensor for downstream applications
• Specific-fit design for BMW exhaust sensor locations
• 4-wire configuration with a male radiused polygon connector
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 21.18
• Overall length: 24.72
• Wire gauge: 22

Detailed Description

Walker Products OE 250-24713 is engineered for BMW oxygen sensor replacement where accurate exhaust feedback is required by the ECU. This sensor is listed for downstream right, downstream left, and downstream front positions across a wide range of BMW vehicles, including 2006-2019 BMW 325i, 328i, 335i, 528i, 535i, 550i, 650i, 750i, X3, X5, X6, and Z4 applications. The part number 250-24713 is also referenced for bank-specific downstream locations such as Bank 1 Sensor 2 and Bank 2 Sensor 2 on select models.

Walker Products OE sensors are developed as original-equipment replacement parts for specific vehicle applications. This helps maintain the diagnostic feedback expected by the ECU while matching the required fitment position, connector style, and threaded installation point.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Fault codes stored in the ECU for downstream sensor circuits
• Poor fuel economy caused by incorrect exhaust feedback
• Elevated exhaust emissions from a failing sensor
• Rough engine operation tied to sensor signal issues

Installation Notes and Tips

Confirm the exact BMW year, model, and sensor position before ordering. This part is listed for specific downstream locations, so bank and sensor number matter. Inspect the wiring harness and connector for heat damage, corrosion, or abrasion before installation, and verify the threaded mounting point matches the original sensor.

For fitment examples, this part fits 2015-2019 BMW 650i Gran Coupe, downstream right; fits 2015-2019 BMW 650i Gran Coupe, downstream left; fits 2015-2018 BMW X5, downstream right; and fits 2006-2011 BMW 325i, downstream.
