I finally got a new O2 sensor and had a oxygen sensor, but when I looked at the extension I bought. Its the wrong one. The one I got is the 4-wire square extension, and my O2 sensor is in a trapazoid shape.
Anybody know where to get one with the trapazoid shape extension?
thanks

I have the same question, I just put Kooks long tubes on and had to relocate the cats now I need o2 extensions. Any one know of a trapazoid extension?

 

Might try caspers electronics.

 

Yea, I was scanning their website earlier and I think the extensions for the newer model vette will do the trick. Im going to pull my o2s in the morning and take a good look to compare them.
