I've been monitoring the IAT via my ScanGuage vs the ambient temp via the auto dimming mirror. I've got the horn removed on the stock airbox. So far the past 2 weeks, the highest temp I've seen out of the IAT has been around 80*F - with an ambient temp of about 50*F, and that was when idling at a long stop light. The faster the vehicle travels, the colder the IAT gets - even down to 30*F on the highway when its ~15*F outside. So far on the street the actual intake temp seems to run at twice the ambient at the hottest while idling. As soon as you start moving it drops.
So it's sucking cold air. Interesting. I'd like to see results of this in the summer as well. Another reason for me to get a scan gauge I guess!
