Walker 350-34610 Oxygen Sensor - Downstream, Downstream Right or Upstream

Walker 350-34610 Oxygen Sensor Overview

Walker Products 350-34610 is a heated oxygen sensor built as a specific-fit OE replacement for select Volkswagen, Audi, and related applications. It is engineered to deliver the diagnostic feedback the ECU expects, helping maintain proper fuel control and emissions performance.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for exact application fitment. The 350-34610 follows that approach with a threaded, 4-wire design and a connector layout matched to the vehicle position.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct application matching
• 4-wire configuration with 22-gauge wiring
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 23.15
• Overall length: 26.69
• Male connector with radiused polygon shape

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Poor engine running caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel correction
• Higher exhaust emissions from delayed or faulty sensor input
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Confirm the vehicle position before ordering, since this part is listed for upstream, downstream, and downstream right applications depending on the model. Inspect the sensor wiring harness and connector for damage before installation, and verify the threaded mounting point matches the 18.0 mm specification. For Volkswagen Jetta, Volkswagen Golf, Volkswagen Beetle, Audi TT, and Audi S3 applications, match the chassis or sensor position notes exactly to the vehicle build.

Walker Products 350-34610 is an OE-style replacement oxygen sensor for specific Volkswagen and Audi fitments, including 2018-2022 Volkswagen Saveiro upstream and select 1999-2005 Jetta, Golf, and Beetle downstream applications. This part cross-references no listed alternate part numbers in the provided data.
