Walker 350-34379 Oxygen Sensor for Acura NSX
Walker Products 350-34379 is a specific-fit heated oxygen sensor engineered as an OE-style replacement for the exhaust system. It is built for the upstream front position on 1997-1999 Acura NSX models and is designed to provide the ECU with the feedback needed for proper fuel control and emissions monitoring.
Key Features
- Specific-fit heated oxygen sensor for the upstream front location
- Fits 1997-1999 Acura NSX, upstream front
- 4-wire design with a 20-gauge harness
- 29.06-inch wiring harness length
- Threaded mounting with 18.0 mm thread diameter
- Male connector with radiused polygon shape
- Overall length: 32.6 inches
Product Details
Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors built for application-specific fitment and ECU feedback requirements. Part number 350-34379 is intended for the upstream front sensor location on the Acura NSX, where accurate exhaust-gas monitoring helps the engine management system maintain the correct air-fuel strategy. This part cross-references standard oxygen sensor applications for the same vehicle position.
On vehicles like the Acura NSX, a worn sensor can contribute to poor running quality, higher fuel use, increased exhaust emissions, or a malfunction indicator light. Because the sensor works with the wiring harness and connector, physical damage to those components should also be checked during diagnosis.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect fuel mixture readings at the ECU
- Rough engine operation caused by inaccurate exhaust feedback
- Increased fuel consumption from a failing upstream sensor
- Elevated exhaust emissions from poor sensor response
Installation Notes and Tips
Confirm the upstream front location before ordering Walker 350-34379. Inspect the connector, harness, and surrounding exhaust wiring for heat damage, corrosion, or broken insulation before installation. Verify thread size and connector style against the original sensor to ensure proper fitment on 1997-1999 Acura NSX models.
Quality Assurance
Walker Products states that its engine management sensors are manufactured under Automotive ISO9001/TS 16949 quality systems and developed as OE replacement parts for specific applications. Since 1946, the brand has supplied oxygen and fuel system components for vehicle service needs.
