Hi, recently i unbolted my exhaust and noticed one of these rear o2 sensors was broken in half and the other looked petty fragile,what are these for and can they be bypassed or do i have to get two of these .. http://www.courtesyparts.com/betasi...-sensorrear-300zx-z32-1990-1996-p-182640.html . thanks in advance
Not O2 sensors You'll be referring to Exhaust Temp sensors - with braided wire running through floor? You don't really need them.
