通用款4.9宽频氧传感器 258017025 替换简便耐用

Is your vehicle experiencing rough idle, noticeably higher fuel consumption, exhaust emissions exceeding standards, or the engine warning light on? These symptoms typically indicate aging or failed oxygen sensors that cannot accurately detect oxygen in the exhaust, causing the air-fuel ratio to be imbalanced. When working properly, this sensor monitors the exhaust oxygen content in real time and feeds back to the ECU to help precisely control fuel injection, ensuring combustion efficiency and compliant emissions. This product is a universal 4.9-wide-band oxygen sensor, OEM number 258017025, compatible with models such as 12575657, 213-1572, and other common models. During installation, ensure the sensor threads are clean, use a dedicated socket to tighten to the specified torque, and avoid over-tightening which could damage threads or wiring.
