Best o2 sensor for alky use

[TheDoughboy]

Should I use a AC Delco or a Denso? I will not be using any leaded fuels with it. I want to put a new one in the new motor when it goes back in.

Thanks,

Ron

Either will be fine.

The only thing that really kills O2 sensors is lead, so if you are running unleaded and Alky it doesn't matter which sensor you use. There is a good thread in the tech section on which last the longest. HTH
