I heard you can pick one up @ your local VW dealer for like $20, is this true? Is it a Bosch O2 sensor, if so, what's the part # that aem has with their kit?

 

they're a little more than that. They might not have the right plug on them either - you might need to repin them to use with AEM/Motec guage.

99 Jetta 1.8T front O2 sensor.

 

Also the AEM sensor has a built in resistor in it.. I think they do that for calibration so that the output of each sensor is correct to what the AEM wideband is reading in..

 

the aem w/b sensor comes stock in the new 05 caddys. the part number on the w/b is a gm part number. I just one from the gm dealership for $67 with tax. Or you can order one from horsepowerfreaks. com. there like $80 on there

 

So it does have a resistor that aem put in the O2? is a GM or Bosch? Any more info would be great, I'm kinda confused

Thats GREAT NEWS Where did you get this info from?

You cannot run the standard Bocsh sensor (like the on off the VW) with the AEM wideband.
And I think GM uses Bocsh but dont quote me on that.

 

GM sensor part #12575657 WORKS
57.11 from GM parts direct and 114.22 from the dealer (Iv been told)
Its the same OEM part # that is on the back of your AEM supplied Bosch sensor
Info can be found here. (must log into AEM forum first)


2000civicsi whats the part # on your sensor?

 

good info
