More Information for STANDARD MOTOR PRODUCTS SG326
  • Standard O2 sensors include dual internal seals to ensure the reference sides stay sealed...extending the life of the sensor.
  • The hex nut is backed away from manifold to allow easier access during removal and installation.
  • The breathable Teflon membrane ensures proper clean air flow. This is important because reference air is compared to the exhaust gases across the sensor element, which generates the sensor signal. Clean reference air improves sensor performance.
