AEM Bosch UEGO Replacement Sensor Universal

AEM Bosch UEGO Replacement Sensor - Universal

AEM builds this Bosch 4.2LSU wideband UEGO sensor as a direct replacement for existing AEM wideband air/fuel controllers, giving you factory-calibrated accuracy without swapping out your whole gauge or controller.

This listing covers the replacement sensor only, compatible with the AEM Infinity Engine Management Systems, 30-4100 Digital Wideband UEGO Gauge, 30-4900 Wideband Failsafe Gauge, 30-2310 Inline Wideband UEGO Controller, 30-2340 4-Channel Wideband UEGO Controller, 30-2340-N Nascar variant, 30-5130 Analog Wideband UEGO Gauge, 30-5143 Analog E85 Wideband UEGO Gauge, and the 30-2320 X-WiFi Wideband/EGT Controller.

Important: each sensor has a laser-etched, factory calibrated resistor built into the connector body. Do not modify or swap this resistor, as it will invalidate the sensor's output.
