奔驰W210氧传感器 A0005408517 高速响应 优化发动机空燃比

If your Mercedes-Benz W210 experiences rough idle, weak acceleration, abnormal fuel consumption, or check engine light on, typical symptom of aging or failed oxygen sensor. When functioning, it monitors exhaust oxygen and feeds back to ECU to precisely adjust air-fuel ratio, ensuring efficient combustion, reducing emissions and improving throttle response. OEM A0005408517; fits W210 series (1995-2002) gasoline engines. Installation tips: operate with cold engine; use dedicated sleeve to remove old sensor and apply anti-seize compound to threads on new sensor to prevent sticking; after installation, clear fault codes and road test to ensure system self-learning functions.
