Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE-style replacements for worldwide vehicle coverage. Part number 350-34360 is built for the correct fitment position and sensor feedback requirements, making it a direct choice for vehicles that rely on accurate downstream or upstream oxygen sensor input. This part number 350-34360 is listed for applications such as Mercedes-Benz C350 downstream left, Mercedes-Benz E350 downstream right, and Jeep Wrangler upstream left/right positions, along with additional Chrysler, Dodge, Smart, and Volkswagen coverage.

This part cross-references select OE-style replacement listings for the same application.

What It Helps Address

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

Installation Notes and Tips

• Confirm the exact position before ordering: downstream right, downstream left, downstream, upstream, upstream right, or upstream left.
• Inspect the sensor wiring harness and connector for physical damage before installation.
• Verify thread diameter and connector shape match the original sensor.
• Use the vehicle’s fault codes and service information to confirm the affected sensor location.
• For fitment examples, this part fits 2006-2011 Mercedes-Benz C350, downstream left; fits 2007-2010 Jeep Wrangler, upstream right; and fits 2009-2010 Volkswagen Routan, upstream.
