Question on O2 Sensor's
I am in the process of installing my AS&M Headers, ( They Finally Showed Up). I need to know does the 93 Z have 2 or 3 O2 Sensors? Also where can I buy new ones? I have looked at Thunder Racing and Summit, but I'm not shore which ones fit my car. Any Info would be greatly appreciated. Thanks in advance for all who reply!


Thanks
Tuff.

Thanks for replying back, thanks for the info. Do you know how many O2's the 93z has? I thought it was 2, but I'm not shore. Any info would be greatly appreciated.

I don't think so.

There should be (1) on each manifold. Before the cat.

There are two O2 sensors before the cat. Also keep in mind that the '93 f-bodies used single wire, non-heated O2 sensors. They should be cheaper If you ever decide to run longtubes though upgrading to heated O2 sensors isn't a bad idea.

Heated O2 Sensor's? Do you only need to upgrade with Long Tubes? Or can I upgrade now with the AS&M's? What is involved in doing the upgrade? Thanks for all the reply's?

I jsut bought to BOSCH O2's yesterday and they were $18 a piece which seemed a little high compared to the AC Delco's that I bought last time but oh well.

I'm putting LT's on my 95...actually a 97 LT1 going into my 95 engine bay...so do I just use both O2 sensor places that are on the LT's and that's it? Sorry for bursting in, but I've been wondering.

Just the two on the headers if you are OBD-I (which a 1995 is).
