Are these compatible or just a good deal? -
A bosch 4 wire narrow band 02 sensor is a bosch 4 wire narrow band 02 sensor. You'll have to cut the pigtail off your old one and splice it into the new sensor. If you plan on having the car forever the smart play is to go down to ford and get the plug and wire it into your car harness, 25$ 02 sensors for life.

I got an OE one for 38 bucks here.

Not worth 13 bucks to me to have to change the plug. Plus an oxygen sensor provides a resistance signal to the ECU. In theory wouldn't soldering or splicing the plug increase the resisitance of the circuit causing an inaccurate signal?
Also the talk of modifying your engine harness to accept the ford sensor, Why? For a part that honestly will be replaced 2 or 3 times in the life of a car? Doesn't seem worth it to me.Comment

That is a smoking deal. I don't see how soldering wires together would corrupt the signal unless you suck balls at it. After all the wire that it plugs in to is soldered in to your ecu. Also if you trace the 02 wire from the plug to the ecu there is a splice just before the ecu.Your signature picture has been removed since it contained the Photobucket "upgrade your account" image.

what about an eta? i think they have a 3 wire system. but i was told that a 90 5.0 mustang sensor works.
this is the one for the eta, 32 bucks
part # 13942 bosch from amazonLast edited by long tall eta; 12-09-2011, 04:17 AM.sigpicComment

Solder is a high resistance connection. For example on my mkIV golf TDI I needed to replace the glow plug harness because it was giving me a CEL. My friend who is a VW tech and has done it a number of times changed mine and used crimp and shrink connectors. Apparently if you solder it the extra resistance can make the ECU think there is still a glow plug issue and still throw a CEL. Check out what happens if corrosion or age causes high resistance in your coolant temp. sensor circuit.
Also to correct my earlier post the o2 sensor provides a voltage signal, over a very narrow range. It is also shielded on the harness side which leaves me to be believe the signal would be very sensitive. I personally wouldn't do anything that could cause a drop in that voltage or corrupt the signal. Maybe I am just over cautious though.Comment

3 Wire, check my post here: http://www.r3vlimited.com/board/showthread.php?t=225505
13942 worked for me. '86 325es
This pic shows the new one on the right, and the old on left:

why dont you just crimp/shrink the ford connector onto the 02 sensor side of the wire thus enabling you to use both ford and bmw sensors. (leaving the engine harness untouched)Last edited by khalild; 12-09-2011, 06:52 AM.

Exactly!
Cut old BMW o2 sensor plug from sensor side. Attach Ford engine side plug to BMW o2 sensor side. BAM! You get a BMW sensor, plug it in. You get a Ford one, plug in your "adapter" and plug in the Ford one. No more bullshit crimping, soldering, etc.
Obviously colors are arbitrary.
As far as resistance, well, I always bought the OEM sensor from Worldpac at cost, so I never have to do this shit.Last edited by slammin.e28; 12-09-2011, 06:34 AM.1974.5 Jensen Healey : 2003 330i/5Comment

where would one get a engine side plug from ford o2 sensor?Originally posted by blunttechComment
