What brand oxygen sensor to use?
 

My Bosch is giving erratic readings on my data log. What is the best to use Delphi, denso, or ntk? Thanks

NTK is the best, also the most expensive. I would just replace the Bosch.

AC Delco, hands down.

I use NTK 3-wire heated. Works good so far. Next time though, I'm going to use an AC Delco AFS-74 heated 3-wire.
