Walker 350-341112 Oxygen Sensor - Downstream Right

OE Replacement Oxygen Sensor

This Walker oxygen sensor is built as an OE replacement for specific applications and provides the diagnostic feedback the ECU expects. It is a heated, narrow-band sensor with a threaded M18 x 1.5 mounting design and a 4-wire square connector layout.

• Heated narrow-band oxygen sensor for accurate exhaust feedback.
• Specific-fit design for direct application matching.
• 4-wire, 4-terminal configuration with female connector and female terminals.
• Threaded mounting with M18 x 1.5 thread size and 22 mm wrench size.
• Walker OE Replacement line for application-specific sensor coverage.

Fitment and Application

Compatible with Acura NSX applications in the downstream right position. Fits 2022 Acura NSX, downstream right. Fits 2017-2021 Acura NSX, downstream right. This part cross-references Walker Products 350-341112 for the same application.

Use this oxygen sensor when replacing a failed downstream sensor that can trigger fault codes, poor engine operation, higher fuel consumption, increased emissions, or a malfunction indicator light. On Acura NSX models, the downstream right sensor helps maintain the feedback the engine management system uses for proper operation.

Installation Notes

Verify the connector shape, terminal count, thread size, and harness length before installation. Inspect the sensor wiring, connector, and surrounding exhaust components for damage before fitting the replacement. Confirm the vehicle uses the downstream right application listed above and match the OE-style mounting location exactly.

Quality Assurance

Walker Products manufactures engine management sensors as OE replacement parts and operates as an ISO 9001 / TS 16949 certified company. The 350-341112 is built for the specified application and fitment position to deliver the required ECU feedback.
