Default o2 sensor

Will 2007 STI rear o2 sensor fit my 2013 wrx? I need a new rear one and trying to buy one used, just not sure if it's compatible. Anyone know? I'm clueless. Lol.

Or what about front one moving to the rear and installing a wideband afr?

Keep the front one where it is. Wideband goes in the rear.

The front or Bank 1 o2 sensor is the primary o2 and how your car calculates fuel trims. The rear o2 sensor checks for Cat efficiency and makes minor alterations in trims.

how do you need a new rear o2 sensor in a 2013? Why not warranty it?

If its the same sensor I'd rather buy it used. Does the same thing? Just seeing if anyone knows if they're compatible. If not no big deal I'll find one on a newer part out.

Call your dealer and cross reference part numbers instead of hoping someone on here knows.

Yeah decided just to replace it with one I know works. Got it from a part out on here so I didn't have to guess about compatibility.
