AEM's Bosch 4.9LSU Wideband UEGO O2 replacement sensor kit includes only the sensor (with attached cable and male connector) and is intended to replace an existing mounted wideband sensor used with AEM Digital Wideband UEGO Air/Fuel Controller Part Number 30-4110.

  • Accurate to 0.1 AFR
  • Never requires free-air calibration when used with an AEM Controller and connector plug.
