Digital Wideband O2 UEGO Kit with BOSCH LSU 4.2 Square Sensor ONLY - no gauge is included. Includes sensor, weld-on bung, connector, wire seals and pins.
*NOTE:
- This 4.2 Square O2 Sensor is used for direct input to AEM Infinity ECUs, and is also a replacement sensor for the older 30-4100 UEGO Wideband 4.2 O2 Sensor Kit w/ Gauge and others.
- The alternate 4.9 O2 Sensor works through the newer 30-4110 UEGO Wideband 4.9 O2 Sensor Kit w/Gauge and communicates with the AEM Infinity ECUs with a 1-wire data connection.
AEM's wideband UEGO air/fuel ratio sensor kit includes a Bosch 4.2 LSU Wideband UEGO sensor, connector plug, pins and plugs, and mild steel O2 bung. This kit is designed to be an installation kit for a sensor used with an AEM Infinity ECU or older 30-4110 wideband air/fuel UEGO controller.
These sensors have a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output. The wideband sensor is laboratory-calibrated at the Bosch factory, accurate to 0.1 AFR and never requires free-air calibration when used with an AEM wideband AFR controller.
- Accurate to 0.1 AFR
- Never requires free-air calibration when used with an AEM Controller and connector plug.
- Specifically designed for use with AEM Wideband UEGO controllers
- Includes sensor, weld-on bung, connector, wire seals and pins
