Yes, FYI if you want a shorter harness on the O2 there is NTK 24325, I have used both the Bosch 17025 and the NTK they are the same, just prefer the NTK since I don't need such a long harness.

Get some copper washers to help index the extender correctly in the bung.

they came with washer

so from what one reading in the instructions I face this hole towards the front into the exhaust stream? Do I need to worry torquing the o2 sensor into the extender? I’ve read online you don’t want them to tight I think I read somewhere 36lbs

I always use thread sealant on them.

Just get it good and tight, and indexed properly. I'd recommend nickel anti seize on the threads since it's stainless threading into stainless.
