IS350 P0031 Code Help
I changed my AFE stage 2 intake to OEM intake and the P0031 code has been going off since. The OBD scanner says it has something to do with the O2 sensors.
How do I fix this problem? Replace the O2 sensors?

It is probably a coincidence that you got that code after swapping the OEM intake back in. The code has nothing to do with the Intake part. I would recommend checking the connection of the O2 sensors first then you might have to replace it. How many miles on the car? Any other mods?

I have nvidia midpipe and F-sport exhaust. It's a 08, 80k miles. Local shop says it will cost $500. $250/sensor.

Sounded like your O2 sensor is on its way out. I dont know why they want to replace 2 sensors? Typically you only need to replace the one that fail. Anyhow, the part is probably $100-$150 and could be done without too much problems. Of course, you could just pay the shop if you have no time to do it.
Here is couple diagrams of the sensor in question
