I did bought wire spark plugs and those ones are very good quality, they're working perfect and I'm very satisfied with this product. I've been buying different products from this brand and tbh they're good high finish products.

It doesn't give you guide on which one is up or downstream and still giving me bad O2 sensors code

The upstream O2 sensors worked perfectly but the downstream O2 sensors would not clear codes. This was after taking it to 2 dealerships telling me the same thing (these O2 sensors are not going to work in this truck). I brought the oem O2 (downstream only) one at a time from the dealership. I installed one and cleared PO2099 code and the PO2097 code came back on. I waited 200 miles before replacing the other sensor. It's been over 400 miles for the first sensor and 200 for the second sensor (still no code).

Upon receipt there should be part numbers that start with "1A." The downstream will be 1AEOS02006, and the upstream are 1AEOS02008.

This will depend on if you are installing the upstream or downstream sensors. Bank 1 is on the drivers side and bank 2 is the passenger side.

I'm not sure about your vehicle, but on our 2019 yukon 3 of the 4 fit. They put 1 oddball in that was backwards to the other 3 with the plug. 1a auto said these would fit my vehicle but when I called them they realized that the 1 was different and gave me a prorated discount. They did make it right. I was happy with the way they handled it. I will purchase from this company in the future. The 3 fit my vehicle perfectly except for the 1 oddball.
