I couldn't find much information about intake air temperature sensors similar to the stock FC one so I thought I'd share my findings skimming through datasheets.
Most affordable and widely available sensor I found: Bosch 0280130039. Fits right in the acceptable IAT sensor resistance range (at least for S4, not sure if S5 uses the same sensor).



Generic GM/Delco Sensor on the other hand sits just above the acceptable range. Readings will be off by about -10°C in the 0-60°C range. Not too sure but I think this will make you run richer? Maybe in a worst case scenario better than nothing.

Excellent sleuthing. One thing I'd like to add is that the IAT sensor is also used on 13B and 20B Cosmos too. Identical in every manner. One thing the Japanese manuals have over the North American ones is a really thorough ECU Terminal Chart with graphs for sensor calibrations, PWM waveforms for things like solenoids, BAC valve, injectors, etc. Now if only there was some clever guy that could read Japanese and translate it...wait that's me

Happen to have those? Would love to get the stock sensors on the S4 set up in Megasquirt properly

I've found that the IAT for an R34 skyline is also within range and pretty cheap

Nissan Part number 22630-44B20, it looks like in the US we get 22630-ED000? if i looked that up right

Just installed the Bosche sensor #0280130039 on my 88 NA. Mounted in the bend up of the intake hose just before the TB and the car runs just fine. I was having a heat soak issue with the stock sensor because I live in the central valley and even at night it's in the high 90s. I have yet to see my idle fluctuate due to heat soak. The sensor definitely seems to work without making the car run strangely though.

Help me understand the advantages to running 0280130039 over the stock IAT on my S4 turbo?

There isn't an advantage. They are looking for acceptable alternatives that will work with the stock ECU due to (non) availability of FC IAT sensors.
