i going to be chaging my o2 sensors this weekend and want to know which brand it the best to go for(i.e. bosch, ac delco),it for a 95 Z
thanks

 

I've used both brands and haven't had a bad experience with either. Most people will probably lean towards the Delcos though.

 

AC Delco.

 

Any decent place to get those? My local parts store wants about 50$ EACH sensor!

 

You can get a good deal on Delco sensors from one of these guys:
Dal Slabaugh: 877-448-5451 or
Jason Cromer: 877-726-8295

The auto parts stores most likely are carrying the Bosch sensors so 50 bucks is about the going rate.

 

Bosch sensors seem to be hit or miss. I definately reccomend the AC delco's.
