AEM Bosch LSU 4.9 UEGO Replacement Sensor

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.

The state of California has determined that certain chemicals used in the manufacture of this product have been known to cause cancer and birth defects.
