I have some NTK o2 sensors in my car. Less than 100 miles bank 1 went back. I got a replacement and then compared them. Same brand, same part number, but they are different.

Is this common? Did I have the wrong one at first? Or do I have the wrong one now? Or same thing just different production dates maybe with revisions?

I have a new set and they look exactly like your old set, ordered within the last year.

They definitely don't look like your new ones.

The plugs I ordered were about a 2 weeks old from RockAuto.

I sent NGK a email. Hopefully they respond tomorrow with some info.

these were back ordered for a bit. Maybe they came out with a new revision. If it fits and works as before I wouldn't worry about it

It fits and works, but not sure how long it will end up lasting. I can't push my car any at the moment because I have a cracked cylinder and its my daily. Hopefully in about 1.5 months ill have my v2 built motor back.

Still waiting for a reply from NGK and hopefully they have the answer.
