This is a replacment wideband O2 sensor that came with a kit i bought used. The previous owner had purchased it and its the wrong one for the PLX kit, this one seems to be for the AEM type and others that use the square plug. The Part number on the sensor is 12575657. This sensor is brand new still with the antiseize and plastic cap on it.
