• Specific-fit design for the listed vehicle applications
• 5-wire configuration with a 20-gauge harness
• Threaded mounting with 18.0 mm thread diameter
• Radiused polygon male connector for application-specific fitment
• Wiring harness length: 21.18 in.; overall length: 24.72 in.

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors built for OE-style replacement use. Part number 350-35009 is manufactured for the specified sensor location and vehicle configuration so the ECU receives the correct diagnostic feedback. This matters on applications such as the Nissan Frontier, Nissan Altima, Nissan Maxima, Infiniti G35, Infiniti FX35, and Cadillac CTS, where upstream sensor performance directly affects fuel trim and emissions control.

This part cross-references no listed aftermarket part numbers in the provided data.

What This Sensor Helps Address

• Check engine light related to upstream oxygen sensor performance
• Rough running or inconsistent air-fuel control
• Increased fuel consumption from incorrect exhaust feedback
• Elevated exhaust emissions caused by a failing sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes and Fitment

Install only in the listed upstream positions and verify connector style, harness length, and thread size before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life.
