  • Rectangular, Four pin, 4 wire connector

  • Direct Fit
  • Correct Connector No cutting or splicing
  • Anti-Seize coating on thread
  • Built and tested to strict quality control standards
  • Some applications use (2) of the same Oxygen Sensors Upstream

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.
