三菱欧蓝德/格蓝迪4G69氧传感器 MD365014 MR578114 直接替换，稳定输出

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.
