I need to replace both upper O2 sensors on my Dec 2001 Jag XJ8. I have found that apparently both LNE1684BA and LNE1684BB are listed as the part required. Could some expert give me some clarification on this??? Thanks Bill W.

 

Several vendors on the forum could help with part # and superseded parts.
(or you can look at aftermarket suppliers)

BOSCH Part # 15627

DENSO Part # 2349016

These are compatible #s
