The people who check IAT's on waterboxers are people who are trying to
figure out why the engine is failing emissions tests. The Digitool
displays intake air temps.

I'm not claiming the oil cooler induced high IAT causes a problem for
the emissions test. I was actually hoping someone else could tell me if
that could be the case. I have seen the unusually high intake temps and
wondered if they could be a factor. It seems vehicle manufacturers go to
some effort to supply the engine with fresh intake air unheated by the
engine.
