where can i get cheap o2 sensors for my 96 z28? (Ac Delco)

 

I got mine from gmpartsdirect and got them the next day. http://www.gmpartsdirect.com/results...umber=25312184

 

i beleive i need 4 seonsor right? are they all the same? the same part #?

 

Yes you'll need 4 and yes there the same.

 

ok someone from gm just called me and told me i need 2 o2 sensor for the left and right manifold which have the part# 25312184 and for the exhaust( one in front of cat and one in the back of cat) which has the part # 25312196.. can someone confirm this please

 

How can you tell if your 02 sensor is bad. My car is missing. Like building up with carbon.??

 

i got the codes.. so thats why im changing em

 

The only difference Ive ever heard was that the wire is a little longer, but try doing some searches on the site to see if someone has asked that before.

 

Those numbers are correct.

The front and rears have different connectors, so no, they are not all 4 the same. The rears are also much more expensive.

 

i justy tried to order form the site u sent me.. but i dont think they do international orders.. i live in canada. do u know any other sites?

 

how many do 94s have

 

Three?

 

93=2 unheated O2s pre-cat
94-95=2 heated O2s pre-cat
96-97=2 heated pre-cat and 2 heated post-cat

 

Is the GM Parts Direct link that game gave the right ones for the front? I plan to do a header swap soon and I wanted to just install two new ones for peace of mind. It's for a 95' Z.

 

Yes. Don't put new O2s on new headers. Wait until the headers have been burned in.
