I know awhile back I saw a disscusion thread on O2 sensors but I just cannot fond it now. I am doing some work on my 93 Z28 and I am replacing the O2 sensors and would like to know what ones are good to go with. I have the stock replacement Bosch 12014 but I have heard they are not the best to go with when you start making alot of performance changes to the motor.

I have the LT1 350 but it has been rebuilt to a 383 LT4. I have the BBK headers and y connector pipe with the bungs for the two O2 sensors just like stock exhaust. If there is any other information needed to determine the best O2 sensors for my application please let me know and I will gladly provide it.

Most go with AC Delco, but I use Bosch with no issues.....

 

I just replaced mine with Delco.

For me, for non-performance/maintenance parts I just go with OEM.

 

Thank you Koolaid_Kid that was the thread I was looking for.

And thank you both importKILLER and n2ceptor for your comments. I agree that OEM is way to go with non performance but my 93 LT1 is modified so I was looking for what would work best with performance. And most places in my area carry the Bosch and I had no problems with the Bosch before the changes made to the engine.

Thanks again for the help,
Jerry

 

Denso is actually the best you can get. You can run them with leaded race gas no problem. They dont really cost anymore then any of the other brands you find. I highly recommend them to all especially people that have problems with Delco's.
