Hello, you are looking at a Oxygen Sensor Standard SG1806. (TWO-03)313-9396. Ford Thunderbird 96. Ford F-150 96. Ford F-250 99 -96. Ford Econoline Super Duty 99 -98. Ford E-350 Super Duty 99 -98.
This O2 sensor is made by a US company (Standard Motor Products) which also happens to be a supplier to major automakers such as Ford. Quality is excellent and equal to the OEM. After installing this in my 2003 Ford Taurus, I checked the operation of this sensor with a scan tool to ensure it was correct. Voltages were to spec and this unit was switching rapidly, all good. Cleared a P0430 code I had been experiencing. Other SMP products I have used, like spark plug wires, have also been of very good quality. I wouldn't hesitate to use this brand in lieu of Motorcraft parts at all.
