Guys,
It would be nice to get more experimental data on this from other vehicles.
It is simple to do. Go out to Walmart and pick up a digital thermometer (they are about $5-$10) like the one below:
Place it at the positions I show above and report your data. Make sure the sensor is not making contact on any surface. We only want to measure the temperature of the air not any metal/plastic surface.
Take a picture of your setup and report your data in this thread.
