Great part and as it says, it is an Exact Fit. Perfect OEM fit and no headaches, other than figuring out how to get a wrench on the old one. TIP: Cut the wires of the old one and used a closed-end wrench. You might round off the old one as they can be tough to get out.
My only criticism is the way the parts are labeled. Not sure if that is Autozone's doing or Bosch. The choices of sensors are labeled as "Right" and "Left". Ford only refers to them as Bank 1 or Bank 2. Right and Left can be confusing as that would depend on how you are looking at the engine. For a 3.5 Ecoboost, Bank 2 is the "Left" part and Bank 1 is the "Right" part.
It only takes a little time and google to figure that out, but would be nice if the same terminology was used.
Replacement only took about 30 minutes and most of that was spent figuring out where to access sensor from and letting penetrating spray work on the old part.
Truck is running so much better and cleared up the code I was getting.
