三菱车系 氧传感器SLDC650-24HU 多车型通用替换

Mitsubishi O2 Sensor SLDC650-24HU directly replaces original factory number; universal across many models, no year restriction, for Outlander, ASX, Lancer, etc. Its core function is to monitor exhaust oxygen content and feed back to ECU to adjust the air-fuel ratio, ensuring combustion efficiency. After installation, it can effectively resolve high fuel consumption, sluggish acceleration, and check engine light issues. When idle is unstable, exhaust smoke from the tailpipe, or noticeably high fuel consumption occurs, it usually indicates sensor aging and requires replacement.
