Then the IAT-related strategies in the ECU can work properly (e.g. spark retard vs. IAT, which is crucial).
I would be very surprised if there wasn't an off-the-shelf ntc air temp sensor with a similar linearisation curve to the one built into the MAF sensor. You will want an open-element one, not solid, for faster response. Just a case of finding somewhere suitable in the plenum to mount it and patch it into the wiring loom/harness.
Let's not bodge stuff chaps!

MAT is an industry standard term. There is even a standard OBD2 code (P1119, etc.) that reference MAT. Some vehicles do have both a IAT and a MAT, like my 7.3L Powerstroke Diesel.
