    Walker Products 350-33065 oxygen sensor for the 1991-1994 Subaru Legacy H4 2.2L measures the oxygen content of the exhaust gas. The upstream sensor reports to the ECU so it can monitor the air-fuel ratio for combustion efficiency.

    • Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gas
    • Electrodes made of a gas-permeable platinum layer
    • Monitors exhaust gases and reduces pollutants
    • 3-wire narrow-band design
    • Made for its specific application and fitment position on the vehicle
