Oxygen Sensors Which One?

[ltheriault]

I have to replace a post converter left bank oxygen sensor on my 1996 GMC sierra 5.7L i'm on e-bay there there are so many brands of sensors from AC delco to Borg Warner. All have different probe designs are there any brand of sensor recommened? Also is there a difference other than plug connection type from a post or pre converter sensor? Thanks.

I really dont buy much if anything off of ebay unless required because sometimes the parts are not right, but you could go factory with the sensors but they are usually expensive when the cheap ones do the exact same thing, ive used NGK's that were about 30ea and had no problems with them but i bought them from the auto parts store so just look around before you go for ebay.

You will be just fine with AC/Delco or Bosch.

I have bought a few things off Rock Auto.. very fast delivery and cheaper than auto parts stores as well..
