Oxygen Sensor Brands

[Southcross]

I've searched... and every "Brand" says their product is superior to "other brands"

seriously... If my choices were Denso, Bosch, or NGK/NTK... and lets say they were the same price, same "universal" wiring... is there a "better" sensor for my buck?

All I know is that for lean-burn-using Hondas the Bosch sensors just won't work because they aren't made precise enough for the rest of the equipment.

At that point I'd go with whatever one is in stock. I really don't think it matters.

thats what I'm thinking.... I'm thinking of going "which ever is least detrimental to my pocketbook"... LOL
I'm just currious if someone out there would say "ya, I had tried two different XXXX and YYYY brands and found that YYYY did ZZZZ"

I've heard the same. For my Saturn, I should have gotten the OEM Denso, but I got a universal Bosch. Maybe once a month I throw a code P0410 (secondary injection system failure/error). But I know from research that this is because the Bosch doesn't respond fast enough during startup testing. I just clear the error and ignore it, but it is annoying.

Unless you have definitive proof about brand "X", I would go with the OEM brand.

OEM brand is Bosch... but I'm "modifying" my setup for better cold FE. You would have to know the caveats of single wire vs multi-wire (heated) O2s. a Heated O2 may improve my FE allowing me to set the ECU to Closed Loop sooner

anywaysies... I'm even contemplating going "Cheap eBay", I think that's what I have in there now (single wire version):
eBay Motors: NEW BORG WARNER UNIVERSAL 3 WIRE OXYGEN SENSOR! (item 150271642570 end time May-11-09 22:10:13 PDT)

3 wire!? I've never heard of such a thing.

[Daox]

1 signal wire, grounds to the exhaust system. 2 wires for the heating element.

[Southcross]

1 - Signal only
2 - Signal, Shield
3 - Signal, Heat & Ground
4 - Signal, Shield, Heat & Ground
5 - typically wideband (don't know the pinout off the top of my head)

I've also considered that and should probably do it. My post-cat is a heated 4-wire sensor.

My reason would be a little different. A while back RH77 reminded me that extensive use of EOC (engine off coasting) can cool the 1-wire 02 sensor and push you more into open-loop conditions. One that stays heated would be immune to EOC.
