Does anyone know if the upstream o2 sensor on an 04+ camry with the 2az-fe motor is the same as the the one on the tC? I 've seen how expensive these can be to replace, but I searched on rockauto.com and they have the upstream sensor for the camry listed as $87 something I think. It is not OEM, but if it is a compatible sensor, it would be less than half the price of the factory one. I'm just contemplating this since I'm gonna be changigng the header soon and am planning ahead for a crossthreaded o2 sensor.

Also, would I be able to use an antiseize compound on the threads or will the heat be too much? Thanks for the info.
