Product details
AEM's Bosch 4.2LSU 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 wideband air/fuel UEGO controllers.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.Replacement Sensor for the following AEM Wideband Controllers.AEM Infinity Engine Management Systems30-4100 - Digital Wideband UEGO Gauge30-4900 - Wideband Failsafe Gauge30-2310 - Inline Wideband UEGO Controller30-2340 - 4-Channel Wideband UEGO Controller30-2340-N - 4-Channel Wideband UEGO Controller - Nascar30-5130 - Analog Wideband UEGO Gauge30-5143 - Analog E85 Wideband UEGO Gauge30-2320 - X-WiFi Wideband/EGT Controller Bosch LSU 4.2 Wideband UEGO Replacement Sensor, Sensor Only Bosch LSU 4.2 Wideband UEGO Replacement Sensor AEM Bosch Replacement UEGO Sensor Bosch LSU 4.2
