路虎极光氧传感器 LR049882 原装位替换 EJ32-9F472-AA

All-new Range Rover Evoque models use oxygen sensor OEM LR049882, also compatible with EJ32-9F472-AA; a genuine universal part requiring no wiring or bracket changes. This sensor monitors oxygen content in exhaust and feeds back to ECU to adjust air-fuel ratio, ensuring combustion efficiency. After installation, it can resolve high fuel consumption, sluggish acceleration, and excessive exhaust emissions. If idle is unstable, engine warning light is on, or fuel consumption suddenly increases, sensor aging/failure is the cause; replacement restores power and fuel economy.
