Stamped with the Ford oval and part number
Identical to the original oxygen sensors on my 2014 Mustang GT at a nice price. Comes with a bit of never seize already on the threads. Do yourself a favor and buy the OEM tool oxygen sensor wrench. You can thank me later.

Compatible with 2013 Ford Explorer Sport.
Installed and the check-engine light went away. Bank 1 Sensor 1 on the Explorer Sport is under the engine near the oil pan. It took about 2 hours to replace and I have been doing work on my cars all my life. Lifted the vehicle, removed the front passenger side tire and was able to access the sensor. What gave me the most trouble was the darn connector. You have to disconnect and connect using one hand.
