I seem to get a text pretty often in regards to replacement o2 sensors and where to get them for widebands so I figured I would just post this for people to make it easy to find on google/ ht search.

the newer style and probably more common now lsu4.9 or lsu 4.9 sensors part number is 17212 and retails for about $60 at orielys autoparts with a one year warranty.



The older style lsu 4.2 square style wideband sensor is part number is 17018, can be purchased at orielys auto parts for between 60-72 bucks usually with a one year warranty. For what it's worth the older style o2 seems to last much longer and is much more durable in my experience.
