Mitsubishi Outlander/Grandis 4G69 Oxygen Sensor MD365014 MR578114 Direct Replacement, Stable Output

If your vehicle shows rough idle, increased fuel consumption, exhaust odor, or persistent engine light, the oxygen sensor is aging or failing. The sensor provides real-time feedback of the air-fuel ratio to the ECU to optimize combustion and emissions. OEM numbers MD365014/MR578114; fits Mitsubishi Outlander and Kluger models with 4G69 engines; direct replacement for OEM. Install on a cold engine; use a dedicated socket to avoid thread damage; avoid contact between sensor harness and exhaust pipe to prevent heat damage. For B2B buyers, this sensor is a factory replacement with strong compatibility, suitable for bulk purchase for repair shops or parts distributors to reduce customer complaints.
