Generic O2 Sensors- does Audi interchange w/ Saab?? [Audi related]

[George Siambis]

Hello all,

TPC quoted me $39.99 yesterday for the 'universal' Bosch 3-wire O2 sensor,
in case anyone will need one soon...obligatory audi content...

If I get the 3-wire O2 sensor that TPC sells as 'universal'* for audis, will
it fit onto an '87 $aab 900s (16v)?  Any BTDT??  Perhaps, I can *carefully*
use the spark plug thread chaser I had used on my audi O2 sensor threads to
confirm this?

The 'universal' sensor from TPC is Bosch #13913, and, according to TPC, is
not a true "universal" but has the connectors for  particular F0rd cars
(thus the price diff?). . . . so all else being equal, clipping off and
crimping on connectors is what makes this sensor universal.  The Bosch
website part locator lists Bosch#13028 for the $aab sensor w/ connector &
#13019 for an 88' 90q sensor w/connector.

I have complete faith that despite all the different p/n's for different
cars, only a couple or very few physically different O2 sensors are actually
made (like an O2 sensor family tree)...or at least I hope so....

Thanks in advance for any help,
George
