I drove home from work yesterday going a differnet route since I had to stop at the store. Here is the data:

Time/Dist……Outside(F)…...Intake(F)……..Filter Box(F)………….…Notes
Start…………………44……………..…37 .7…………..…….39.6.....Outside temp higher due to thermometer being in sun
1 min………………. 44………………...37.1………………..38. 7....Idling
1.5 mile…………….37.8……………….37.6… ………......37.2
2 mile...…………….36.2………………36.5â €¦â€¦â€¦â€¦â€¦â€¦â€¦36.2
7.7 mile………………36…………………35.5â €¦â€¦â€¦â€¦â€¦â€¦..43……Stopped at store, < 10 min.
Start................37................35.5....... .......69.4
1 minute............?....................?.......... ......65.3.....Driving thru town, 20 mph, from Start to 3.5 minutes
1.5 minute..........?....................?............ ....60.....? - Couldn't write temp while driving
2.5 minute..........?....................?............ ....53.8
3.5 minute, also 8.8 mile.............?................50
19 mile...............33..................35.6....... .....44

After leaving the store, I stomped on it a few times for a short distance, (you can't get up much speed on these back roads,) and the temperature started decreasing. So you can see, with the temperature in the mid 30's, the stock air setup is going to run about 10 degrees higher than outside air due to heat generated from the engine. The air entering the stock intake is the same temperature at the outside air. Insulation around the air filter box may help reduce the temperatures.
