Well of course I may be wrong
But given that the air outside is liable to be lots less hot than the air inside the engine compartment and given that the air is passing quickly through the intake plumbing which should keep the plastic cool (except after the car has just been shut off when the radiated heat would not be countered by the incoming cooled air until the car had been running for a while) ...
I still am curious how you measured it as 40 degrees cooler after wrapping? Under what conditions were the measurements taken (was the engine compartment cover shut, how long had the engine been running and were the measurement taken with airflow going on because the car was moving)? And where were the measurement points?
I'm the resident skeptic and old enough to remember "trust but verify".
