Walker 350-35014 Oxygen Sensor - Downstream, Upstream or Upstream Right

Walker Oxygen Sensor for Volkswagen Applications

Walker Products 350-35014 is a heated, specific-fit oxygen sensor engineered as an OE-style replacement for select Volkswagen models. It is built for the correct application and mounting position, helping the ECU receive the feedback it expects from the exhaust system.

Fits 2004-2013 Volkswagen Beetle, downstream or upstream depending on model year and engine application; 2004-2006 Volkswagen Golf, downstream; 2004-2005 Volkswagen Jetta, downstream; 2004-2005 Volkswagen Passat, downstream; 2006-2008 Volkswagen Touareg, upstream right; 2006-2010 Volkswagen Jetta, downstream; 2011-2013 Volkswagen Clasico, downstream.

Product Details

Walker Products 350-35014 is part of the Walker Products Aftermarket engine management and oxygen/air-fuel sensor line. The brand develops these sensors as direct replacement parts for many vehicles worldwide, with application-specific fitment position and ECU feedback requirements in mind. For Volkswagen Beetle, Jetta, Golf, Passat, Touareg, and Clasico models, this sensor is intended to restore proper exhaust monitoring at the specified upstream or downstream location.

This part cross-references Bosch 15717 for the same application.

What It Helps Address

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

Installation Notes

• Verify the exact position before ordering: downstream, upstream, or upstream right.
• Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.
• Confirm thread size and connector style match the original sensor on the vehicle.
• Use the vehicle’s service information to identify the correct bank and sensor location.

Quality Assurance

Walker Products has manufactured engine management and fuel system components since 1946 and operates as an Automotive ISO9001/TS 16949 certified company. The 350-35014 is built to meet the application-specific requirements of the listed Volkswagen fitments.
