Keep the ECU's fuel trim dialed in with the Walker Products Oxygen Sensor 350-34634, a 4-wire heated narrow-band sensor that measures the amount of oxygen in the exhaust gas to gauge combustion efficiency. It drops in as a direct-fit, OE-style replacement across a wide range of Infiniti, Nissan and Renault applications — including the 2007-2012 INFINITI FX35 [V6-3.5L], 2008-2013 INFINITI G37 [V6-3.7L], 2007-2009 NISSAN 350Z [V6-3.5L], 2008-2013 NISSAN ROGUE [L4-2.5L] and 2009-2016 RENAULT KOLEOS [L4-2.5L]; see the Buyer's Guide tab for the full list of 58 applications and engine codes.
Narrow-band, 4-wire heated design: reads the oxygen content of the exhaust gas so the ECU can monitor the air-fuel ratio for combustion efficiency.
Platinum electrodes: built with a gas-permeable platinum layer for accurate sensing.
Protective coating: helps prevent contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust.
Emissions monitoring: tracks exhaust gases and helps the ECU maintain the correct air-fuel ratio for normal fuel economy.
Every part number is engineered for the specific application and fitment position and delivers the diagnostic feedback the ECU expects. Signs the original sensor may need replacing include an illuminated malfunction indicator light (MIL), poor running, or increased fuel consumption and emissions — inspect the sensor, wiring harness, and connector for physical damage as well. Threaded mounting with a 475 mm wiring harness and a 22 mm wrench flat. Country of origin: China. Manufacturer part number 350-34634 (also 35034634).

Frequently Asked Questions
What does this oxygen sensor do?
It measures the amount of oxygen in the exhaust gas so the ECU can monitor the air-fuel ratio and gauge combustion efficiency, sending the diagnostic feedback the engine control system needs.
Will this sensor fit my vehicle?
It's a specific-fit, OE-style replacement covering 58 Infiniti, Nissan and Renault applications, such as the Infiniti G37 [V6-3.7L] and Nissan Rogue [L4-2.5L]. Check the Buyer's Guide tab for your exact year, model and engine.
Is this a heated, narrow-band sensor?
Yes. It's a 4-wire, heated narrow-band oxygen sensor with spade terminals and a square female/male connector.
What are signs the original sensor may need replacing?
An illuminated malfunction indicator light (MIL), poor engine running, or increased fuel consumption and emissions can indicate a failed sensor. Also inspect the sensor, harness and connector for physical damage.
How does it install?
It threads into the exhaust and tightens with a 22 mm wrench, and comes with a 475 mm wiring harness. Consult the vehicle service information for the correct torque and procedure.
