IAT's with Stock vs Airaid

I've only been running with the stock airbox for a little more than one week so I imagine there's a lot more for me to learn but......for what it's worth I'm a little surprised/disappointed by what I'm seeing so far. First of all there is some very noticeable differences, just not what I'd hoped. The temp swings are much slower and somewhat smaller most of the time. In extreme conditions ....say persistent gridlock, the high temps are essentially similar. Baseline over the road I'm recording slightly higher temps 2 to 3 degrees).  I think that might be from whatever variances there may be in sensor location, orientation between the two installations. The stock box is slower to rise but holds on to the higher temp longer than Airaid.  I may not be very discerning but I  hear no difference soundwise going from Airaid to stock and while i have not done any dyno, or 0 to 60 runs, my butt dyno feels pretty much the same.  I'm now thinking for round 2, a simple way to lower heat soak and IAT, might be to install the 170 degree stat. That seams to be a win win.  I'll be able to tweak the tune for the colder stat I think I read of a little more power potential, and those who have run this temp stat through the winter report plenty of heat from  the heater is still available. Have to give some thought to possibly moving/extending the snorkel source to somewhere further upstream and more thermally isolated than stock....just thinking at this point.
 
Do some datalogs for 0-100mph (if you can) runs. Based off what myself and others saw at the track I have to imagine the Airaid has higher IAT than stock
 
Very interesting Larry.  I too would like to see a direct comparison.  At this point, I think there are pros and cons for both set ups.  I doubt there is a substantial difference between them performance wise. It seems to depend on generating and dispersing heat. 
 
The further you can get your intake from the engine, the lower the IAT, and heat sink.  The AirAid is a great looking CAI, but the filter end seems to block intake air.  When I tested one for a few days, my IAT temps were several degrees higher than my custom CAI, which sucks air from back of the drivers side headlamp, and has a diverter to keep engine heat from it.

At HWY speeds my IAT temps are at Ambient temp.  Still... key is MCT (Manifold Charge Temp) not IAT.  That's why a W/M system works as well as it does, by lowering MCT.
