AEM Bosch LSU 4.2 Wideband UEGO Replacement O2 Sensor
Wideband O2 Sensors are a wear-item. They don't last forever, and many different factors can cause them to fail earlier than others. When you do finally have one fail, you can purchase just a replacement sensor for the wideband controller, without having to buy a whole new wideband. This Sensor is a plug and play replacement for all AEM widebands.
This kit includes a Bosch 4.2LSU sensor for use with any AEM Wideband UEGO Controller or Gauge.
The Bosch 4.2LSU sensor, which gives AEM Wideband controllers their speed and accuracy, is laboratory calibrated at the factory and never requires free air calibration when used with an AEM controller!
No free air calibration required - ever
Accurate to 0.1 AFR
