Default o2 sensors

2003 Vert, 136K - While I have the exhaust pipes out, any recommendations for a brand of O2 sensors?

Aftermarket (non OEM) parts especially electrical are not made to the same QUALITY standards as the original...O2 sensors, MAF sensors, cam and crank sensors etc !!...you couldn’t pay me to put a Dorman part on my car !!

I used NTK's on my car. My wideband for tuning is also an NTK. I also would have no problem installing Bosch Parts.

I use Denso 02's on all my GM vehicles because they are consistently the best. AC Delco would be my 2nd choice.
