AEM UEGO Replacement o2 Sensor - 30-4110
This is a replacement UEGO wideband sensor for the newer 30-4110 wideband (4.9 LSU). This will not work with the old model 30-4100. This sensor is the same as AEM part # 30-2004. If your AEM wideband sensor has been damaged, this is an economical replacement for you.
