AEM replacement
To those who are looking for an AEM wideband replacement, this review is for you!This is the exact fit replacement for your failed AEM sensor.The harness is shorter than what came with your wideband, but it is the exact replacement for my X series 30-0300.Works perfectly and is able to be read by my gauge and ECU with no errors.Stock up on a few before prices go up and never have to worry again.

Works as it should
Fits on 2016 explorer, no more engine code so works good.

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.

Used Dirty Sensor
I received a used oxygen sensor. The plug was dirty and the sensor was covered in soot from installation and use.

Perfect replacement
Matched the oem identically. We won't go into the replacement aspect of this horrid job so no bad rating for that. However, the price dropped the day after I purchased this by like $11. I contacted customer support to see if they could price adjust/match by some miracle. Absolutely no response from customer service which makes it even worse than a simple no. Of course I had to purchase another one because I replaced the wrong bank and mangled the old one. This time woth the new price, shipping is very slow on the new one (2 weeks) compared to the 2 day previously. In the future I will more than likely purchase from another vendor.
