Walker Products Oxygen Sensor P/N:350-35049

Give your engine accurate exhaust feedback with the Walker Products Oxygen Sensor 350-35049, a direct-fit Hyundai Tucson oxygen sensor that also serves the Kia Sportage. This 5-wire wide-band sensor installs in the upstream position and measures combustion efficiency based on the amount of oxygen in the exhaust gas, monitoring the air-fuel ratio so the ECU can fine-tune the mixture.

• Wide-band, 5-wire upstream design: determines the oxygen content of the exhaust gas to track air-fuel ratio for combustion efficiency.
• Platinum electrodes: built with electrodes made of a gas-permeable platinum layer.
• Protective coating: helps guard the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust.
• Emissions monitoring: reads exhaust gases to help reduce pollutants and support normal fuel economy.

Each Walker part number is made for the specific application and fitment position and provides the diagnostic feedback the ECU expects. A failing oxygen sensor can make the engine run poorly, raise fuel consumption and emissions, or trigger the malfunction indicator light (MIL); if a worn sensor is the cause, this replaces it. Inspect the sensor, wiring harness, and connector for physical damage during service.

Fitment: 2010-2013 Hyundai Tucson; 2011-2013 Kia Sportage. See the Buyer's Guide tab for engine details.
