Bosch LSU 4.9 UEGO Replacement Sensor

• Universal

The AEM Bosch LSU 4.9 UEGO Replacement Sensor is the direct replacement wideband sensor for the AEM 30-4110 Digital Wideband UEGO Gauge. The sensor is laboratory calibrated at the Bosch factory, is accurate to 0.1 AFR, and never requires free-air calibration when used with an AEM wideband AFR controller. A laser-etched, calibrated resistor in the sensor connector body is created specifically for the exact sensor it is attached to; modifying it will invalidate the sensor output.
