  • Rectangular, Four pin, 4 wire connector
  • Replaces one of many dealer part numbers including: 25315809, 8-25325-266-0, 8253252660, 25133504, 19178930, 25165313, 25312184, AFS105
  • Direct Fit
  • Correct Connector No cutting or splicing
  • Built and tested to strict quality control standards
  • Some applications use (2) of the same Oxygen Sensors Upstream


Note: For clarification purposes:

  • Upstream location is between the catalytic convertor and the engine
  • Downstream location is between the catalytic convertor and the tailpipe


A direct replacement. If you have a bad O2 sensor causing your vehicle to idle poorly or fail an emission test then this is the part for you.

Note:  You may be required to reset the vehicle’s computer after installation of this part.
