best or good O2 sensor

[T-Type85David]

I was just wondering, what O2 sensor to go with, that heated O2 looks ok, so does the GNX one, who sells the GNX O2? Just wondering what people use or feel that works best.

You will find opinions all over the board on this. Pick one and go with it. I personally have dropped them all and gone with a WB o2 and control the A/F ratio through the chip. Good luck- Brad

Just did all that research

I have alky, and Julio recommended the AC Delco AFS-21. Paid way too much for it IMO.

IMO Denso 264-1001 they last the longest
