I'm Just replacing ALL my o2 sensors now because - well 130 K and it's about time.
So Can anyone give me a DEFINATIVE well documented reason NOT to use chineese o2 sensors?
I know Bosch- Denso - NGK - Walker - are supposed to be better but is there any reliable PROOF of this?

As I understand the platinum layer is spec'ed for useabillity by aftermarket units and I dont think any MAJORS would use more than minimal necessary coatings or components.
So is there Documented not anectdotal PROOF that one is better than another?
Just trying to dispel any lingering apprehensioin or misinformation .
Thanks

I don't really have an answer for this but I have replaced my Corvettes O2's with Bosch and it fixed a NOX issue. You could be our beta tester for Chinese ones.
