Kevin in Atlanta

I would like to have two O2 sensors next or near each other on an X pipe - one for NB and one for WB.

Are there any problems mounting them in the same steam and any suggestions for how far apart they should be?

Hi Kev,
I have no direct experience, but the engineer in me says you should not put them in line.
It might work, but it's likely that the upstream sensor will disrupt flow to the downstream one.
I would definitely try to space them out radially around the pipe, if at all possible.
Even a small amount of angular offset from each other should make a big difference.
And I think if they're clocked differently around the pipe, they can be placed close together.
