Industrial O2OxygenSensor1And2XO Oxygen Sensor

The O2 Oxygen Sensor 1 & 2 set for the 1997–2004 Mitsubishi Montero Sport 3.0L V6 provides upstream and downstream oxygen sensing for precise air-fuel ratio control and catalytic converter monitoring. Sensor 1 upstream delivers real-time feedback to the ECU to adjust fuel mixture, while Sensor 2 downstream checks catalyst efficiency, supporting emissions compliance and OBD-II diagnostics. This heated zirconia sensor pair features an integrated 12V heater for fast warm-up, M18 x 1.5 threads, a stainless steel body with a ceramic sensing element, and an OEM-style sealed connector designed for high-temperature exhaust environments. Compatible with 1997–2004 Montero Sport 3.0L V6 (6G72), the set serves fuel-injection systems and emissions-related repair, particularly where accurate oxygen measurement is required. Common replacements include Denso OEM oxygen sensor set for Mitsubishi 6G72 3.0L V6, Bosch direct-fit upstream & downstream O2 sensor pair, and NTK/NGK OE replacement oxygen sensor kit for Montero Sport 3.0L.
