Detailed Description

Walker Products 350-35032 is designed for vehicles that rely on accurate oxygen sensor feedback to manage air-fuel ratio, emissions output, and diagnostic monitoring. When an oxygen sensor begins to fail, the engine may run poorly, fuel consumption can increase, emissions can rise, and the malfunction indicator light may illuminate. This sensor is built for the listed upstream right, upstream left, upstream rear, and upstream positions across select Porsche 911, Boxster, Cayman, Cayenne, Macan, and Volkswagen/Audi/Ford applications.

This part cross-references no listed alternate part numbers in the provided data. For shoppers searching by fitment, this is a direct replacement oxygen sensor for 2010-2019 Porsche 911 upstream right or left, 2015-2018 Porsche Cayenne upstream right, and 2015-2016 Audi A8 Quattro upstream applications. It also covers select Volkswagen CC, Passat, Jetta, Beetle, Bora, Phaeton, and Ford Fiesta listings. Use part number 350-35032 when verifying the exact sensor position and connector style.

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 control
• Higher exhaust emissions from a failing upstream sensor
• Fault codes stored in the ECU for sensor-related diagnostics

Installation Notes and Tips

Confirm the exact year, make, model, and sensor position before ordering. This sensor uses a threaded mount and a specific connector configuration, so match the harness length, wire count, and connector shape to the original part. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since damaged wiring can shorten sensor life and affect diagnostic readings.
