Hey Everyone,
I am putting an 02 Sensor on my car and was wonder where it will give me the most accurate reading? I was thinking in the header collector, but wasn't sure. Let me know.

If I'm not mistaken I think most people put them in the collector.

If the headers are not multiple piece, or slip on collector put it in the collector, just not in the 6 o'clock position. Any air that leaks in at slip joints will throw your reading way off, so if it's pieces put it in the lower part of a solid tube. and use that one cylinder as a guide. One piece headers are best for collector installs.

In the collector... 3 oclock or 9 oclock so it doesnt
hold water, in front of the evac (up stream) if using
one but try to get it in the flow of all the tubes
for the best average reading, like was said slip on
collectors can cause air leaks and give a false reading

It should be placed in your bung hole.

Funny "Best Placement for O2 Bung?"

Shoulda read the title.

I was wondering about the position, so thanks. These are 1 piece headers, and I am putting in a wideband. Thanks guys.

Anybody have pics? Is it best to have two(1 in each header) or will 1 be sufficient?

I was also wondering if one is good enough or not.

You have to look close, but you can see both mine near the tranny pan.

Agreed one for each side, run one side one pass then the next side. Lots of things can cause a need for jet stagger from side to side (intake/heads etc). I run mine at 9 and 3 O Clock on both sides. The car is street/strip so rather than mount it in the header I mounted it in the collector/reducer. I believe I read somewhere that the 02 sensor needs to reach a certain operating temp to work correctly, so put your bung hole as close to the collector as possible. Funny thread ...

I did not know that, thats what happens when you get past 40; info over load. In that case I guess you could put your bung hole anywhere.

If you look at how many wires it has, 4 or more wires
was a heater(the old single wire O2 didnt have a heater)

I have mine in the exhaust pipe(street car) just after the collector on the full exhaust and another set in the colletor extensions for at the track testing with open headers, no difference in readings between the two I started out with a LM1 and then bought a FAST system with the dual wide band reading, I have since bought the LC1 upgrade for the LM1 do to its data logging and transferring ability which the FAST system does not have Thank twice and avoid buying twice

You done with that thing yet?

Don't run the O2 sensor unheated, you'll toast them quick.
