Univ Bosch OXS sensor in 12v6???

[Todd Phenneger]

Jim,
  Thanks for the information. It seems the front vs rear sensors
on the V6 are different.  I spose maybe the difference is that
one is sealed and one not.  I'm hoping the forward ones (the
ones I have to replace) are the un-sealed and the post cat ones
sealed.  (would make sense to have the one down by the belly of
the car be sealed.  But who knows.
  Anyhow, thanks for the informative reply Jim.
