雪佛兰氧传感器 96958775 9001347 90765471 原装替换品质

When your Chevrolet engine warning light is on, fuel economy rises abnormally, or idle shakes and acceleration is weak, this is usually a sign of aging or failed oxygen sensor. In normal operation, it monitors oxygen content in exhaust and feeds data back to the ECU to precisely control air-fuel ratio, ensuring combustion efficiency and emission compliance. This product fits many Chevrolet models; original OEM numbers include 96958775, 9001347, 90765471; can be replaced directly. Use a dedicated socket during installation and avoid contact of sensor harness with high-temperature exhaust; prior to installation clean threads and apply anti-seize.
