IAT in maf? tsp 100mm?
how much air the IAT sees going by or if it's in some
backwater corner that is more conduction-heated
than air-cooled.
Out of the engine bay entirely, is better. Extending
the wires of the in-lid-IAT sub-harness is easy.
and tuck it up under the cowl plastic grating. The spot
gets warm sitting in direct sun but not bad.
Out in a wheel well, or in one of the "nostrils" would
not be bad. You just want outside air that has little
or no heating from the engine bay.
