Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE replacement parts for a wide range of vehicles. The 350-341063 oxygen sensor is built for the Mercedes-Benz G65 AMG and is positioned for downstream use on either side, helping maintain the feedback the ECU expects from the exhaust monitoring system. The sensor uses a heated design, 4-wire layout, radiused polygon connector shape, and threaded mounting for application-specific installation. Walker Products 350-341063 is a practical choice when replacing a failed downstream sensor on a 2016-2018 Mercedes-Benz G65 AMG.

This part cross-references no listed aftermarket part numbers for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust feedback
• Elevated exhaust emissions from a failing sensor
• Rough engine operation tied to incorrect ECU sensor input
• Stored fault codes in the ECU for oxygen sensor circuits

Installation Notes

Fits 2016-2018 Mercedes-Benz G65 AMG, downstream right. Fits 2016-2018 Mercedes-Benz G65 AMG, downstream left. Confirm the connector shape, wire count, thread diameter, and sensor position before installation. Inspect the sensor wiring harness and connector for physical damage, since damaged components can shorten service life and affect signal quality. Verify the downstream location on the vehicle before replacing the sensor.
