Replacement Oxygen Sensor

[seascooter]

Can anyone help. I have a 1998 BMW 528I and I need to replace all 4
Oxygen sensors. I remember reading somewhere that I might be able to buy Bosch Oxygen sensors from another car and just splice the connector to fit on my car since the Oxygen sensor itself is the same (if I recall, it was for a Ford). Can anyone help me out with your advice. Thank you very much!! :p

i seriously doubt that all 4 went bad at the same time, the two post cat sensors hardly ever go out, the pre cat sensors generally don't go out at the same time unless you ran a few tanks of leaded gas through it, if you are getting 02 sensor codes from the computer it's a good chance theres another problem, that cars version of a pcv valve can cause bad running and make it throw 02 codes, so can air leaks and misfire's due to oil in the plug tubes shorting the coils and or worn out plugs
