Hi all, what are the advantages/disadvantages for the 2 types of O2 sensor? ie which ones better, the 4 wire or the single wire.
Anyone know why Holden changed over?
Cheers Dre

Hi Dre,
i believe the single wire ones are heated by exhaust gas, and the multiple wires are self heating.. heating up quicker will give u more accurate readings sooner after start up Im assuming.

Thanks for the info. I cant actually leave it as it is as I'm talking about the 308 in my kingswood (which I am in the process of putting an EFI manifold in place of the quad etc).
I have the bung in my extractors for an O2 sensor, so I'll just u
