Lol.....you are not the first to do this mod.
I used a coat hanger....ghetto I know!
In regards to air temps.
I have been logging intake temps in 72F weather and find that at constant cruise low throttle around 2-3K rpm my intake temps sit around 89 to 90F.
During WOT my temps drop as low as 86 during a full 3rd gear pull from 3K rpm.
Not bad for a DCI setup.
Even with a cold air intake setup, your ambient air is going to pick up some heat travelling past the turbos.
I had the stock CAI on last week and noted about a 5 degree improvement over the DCI's at times, but the DCI's are less restrictive and have better throttle response.
They also pull a little harder at higher rpms which is where to stock CAI restriction becomes more of an issue.
A CAI might be better at heatsoak recovery though, since you would be pulling in cooler air immediately to help bring the intercooler temp back down.
But I found that I could get my intercooler back down from 106F to 89F just by using half throttle or so for a couple of gears.
The key is to get airflow into the intercooler.
This is with an aftermarket intercooler though.
