Yes, the old one was a Bosch, maybe 70K miles old? It was still working fine, but I have heard that Saturn ECM/PCMs don't like Bosch 02 sensors because they are "lazy" at switching as compared to the OEM Denso sensors. Today I have an NTK sensor, and it's heated as one of my mods. It seemed like the ECU/PCM needed some time to "learn" about the new sensor, but everything is going well right now.
