Coupe 6MT Premium RAS
Nissan part number 226A0-AM601
However I would just use a reputable aftermarket like a Denso, Bosch, Hitachi, etc.
As for the replacement, I STRONGLY recommend you get under the car and soak the welded bung in PB Blaster for 3-5 consecutive days to try to draw some of the penetrant up into the threads, they can be extremely difficult to remove on some vehicles. Don't try to do it with the exhaust hot this is something you want to do on a 100% cold engine that hasn't been started that day.
Worst case scenario you will be cutting the entire bung off and welding on a new one (quicker and easier if you have a welder, if not any muffler shop should be able to do this for you) Be sure to use high-temp anti-seize on the threads of the new one. thread size should be M18x1.5 for the new bung but double check on the new sensor.
