This part cross-references no listed aftermarket part numbers in the provided data. The Walker Products 350-35008 is manufactured for application-specific ECU feedback, helping maintain proper air-fuel monitoring on vehicles that rely on accurate oxygen sensor input.

What It Helps Address

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

Installation Notes and Tips

Confirm the exact year, make, model, engine, and sensor position before installation. This part is listed for upstream, upstream left, upstream right, and upstream rear locations depending on the vehicle. Inspect the sensor wiring harness and connector for damage before replacement, and verify the threaded mounting location and connector shape match the original unit.

For Mercedes-Benz C200 and SLK200, as well as Volkswagen Jetta and Golf applications, match the listed Bank 1 Sensor 1 or front oxygen sensor notes where provided. On BMW and Porsche applications, verify left or right upstream placement carefully before ordering.

Quality Assurance

Walker Products states that its engine management and oxygen/air-fuel sensors are developed as OE replacement parts and manufactured under Automotive ISO9001/TS 16949 quality systems. The brand has supplied engine management and fuel system components since 1946.
