    From my experience for engine 5252S (10 valves) works only original NTK
    from dealer. Spent a lot time and money for Bosch universal but in vain.

    To answer your question, the signal wire is black, the ground is gray and the two whites are heater wires

    Is your universal a Bosch sensor? if so, then the color of the wires shoud be the same as your original, just splice and connect and use heat shrinking tube,

    The bosch universal is PN# 15717

          $47 is a very good price but I've heard a lot of problems with people using the universal O2 sensors

          You car a turbo or N/A ?

            What kind of problems have you had? Where can I find out more? I started the engine after the new sensors were installed but now I can not get the engine to start???

              My original sensor was NTK (Titania, red, yellow,black and white wire) I thought
              it is regular most common zirconia oxygen sensor and tried to use Bosch universal
              sensor. If you installed appropriate sensor only what you have to do is to reset
              computer and must be O.K. If there is some problem with sensor computer continue
              to work taking information from stored memory. I drived car two weeks without
              oxygen sensor, mixture was very rich (no feedback).
