Walker Products 350-64005 oxygen sensor for the 2006-2010 Subaru Forester H4 2.5L and other vehicles measures the oxygen content of the exhaust gas. It is built for its specific application and fitment position, and it gives the ECU the diagnostic feedback the system requires.

• Monitors the air-fuel ratio in the exhaust gas to track combustion efficiency
• Monitors exhaust gases and helps reduce pollutants
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
• Electrodes carry a gas-permeable platinum layer
• Coating prevents contamination and erosion of the electrode surfaces from combustion residue and particulates in the exhaust gases
• Wide-band, 4-wire air-fuel ratio sensor
