I haven't installed them yet but the DOWNSTREAM sensors pictured are for 2011 Ford Expedition with 5.4 Triton V-8 only . These are the sensors located in the catalytic converters. The top sensors have a different connector (square shape). They appear to be of good quality and well packaged. I'll update the quality info after I install it and ride it a bit.
