Chevrolet Oxygen Sensor 96958775 9001347 90765471 Original Replacement Quality

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.
