That would be nice, but my findings (on another motor) don't quite indicate that... Different set-up but many similarities. This is an Audi TT with the temps measured at the mouth of the CAI inlet.

hot differential: No extra front ventilation
cold differential: ventilation similar to my Fang Vents run to the CAI inlet
Trim: Removing the rear gasket between the hood and firewall to promote airflow through there..

35 minute Test run from start, through a little traffic, some country roads, then traffic and 5 minutes idle in the driveway. These are the temperature differentials from Ambient (70 degrees on the day of the tests). Temperature dattalogger sampling once per minute.

The fact that we can only get IAT's down to within 7-10 degrees of ambient on the 370, no matter what the intake or feed system, would indicate that heat in the engine bay is a factor, even underway...You just have to deal with it as the IAT sensor does..Remember, the engine is running ap 180-190 degrees (Coolant system regulated) Not all that heat is expelled at speed..

Pull that rubber trim off to promote ventilation through the rear of the engine bay results in some nice temp improvements as you can see!
