i know running a smooth pipe to the stock air box, running a drop in k&n, and cutting out the bottom of the box has been proven to have colder iat's then most cai's, but idk if anyones noticed any hp gains doing that...i wish i wouldve done this on my truck before i bought my cai, i just didnt know about it....
I wouldn't have sold a cold air kit due to heat soak.. Heat soak happens more so when you shut the truck off, let it sit, rather then driving it.. Still better then the stock set up..
when i stop at a red light and the iats go up past 155* and takes a good 5-7 minutes of driving at 60 mph to cool down
I could drive 15 to 20 minutes threw town red light to red light stop touch the heat shield it will burn you....could not hold your hand to it
I went over all parts of the coldair intake with a temp gun to find my hot spot

Something doesn't sound right about that. If your underhood temps are that high in general, there is more problems with heat than just the tube and shield. I had the same kit before I put the turbo on, never ever had a problem remotely close to that.
