with only 75k, I bet they are original ones. you can get a bluetooth obd2 reader and use the torque app to figure out what is going on with the cpu. look at fuel trims and vacuum.... if the fuel trims are off, there is a reason and you can discover it with that app.
I was having trouble editing my signature to update the mileage, but it is fixed now. I don't own a smart phone so I don't have apps to use with that type of reader.
They are most likely OE. I can't find any record of them getting replaced. I have replaced the plugs, coils, and wires. Also the PCV and Purge valves. I will try those O2 sensors next.
Denso or NTK O2 sensor only please. These trucks don't play nice with other brands.

They should be shipped here today. I bought the more expensive ones before you posted and they are NTK. Thank you for the confirmation I bought the right brand.

2006 2500 long bed 4x4 with Jasper rebuilt hemi, 10 mpg without thinking about gas mileage, 9 mpg with 1500 lb camper on it. Oddly enough, when I'm crawling on BLM roads I still get almost 9 mpg.
Since my last post I am back to 10mpg and I am considering replacing the exhaust system along with the catalytic convertor.
Maybe this truck needs an enema.
