This can be a trick question. I know the AFE big boost can have a shroud around it, but it's 12th man loud. S&B is a nice breather for my 400 HP, and reasonably quiet with the notoriously-loud 38R. The AIS is a nice breather - it will take anything the stock sticks and turbo will throw at it, even when chipped (with the fender mod). It is also the quietest CAI I've heard. I don't do Banks - they are too proud of their stuff for my taste.
I did not mean it to be a trick question. I have seen
some systems that don't have a shroud and they can only be pulling hot air from inside the engine bay. I want air that is ambient temperature, not closed engine bay temps. Which system seems to seal the best against the hood and draw most outside air? I will look up the ones you listed. Thanks again.
I've used the AIS & 6637 air filter setups (zoo dad mod as well as DI's larger intercooler) I have not seen that much of a difference in manifold air temps between the two. The only difference is at a stop with the engine at normal operating temps, then the intake air temps & manifold temps are higher than ambient. But once rolling down the highway manifold air temps pull back down within 5-10 degrees of ambient temps.
Yeah... a purist may want the CAI for performance factors alone, but the open element does just fine in real-world conditions. I will say that the CAI avoids oil vapors from the engine bay if they exist (my engine bay is downright arid, but I have the stock CCV configuration). There is one key difference between CAI and open-element that is undeniable - sound level under the hood when the go pedal is utilized.

definitely, that is why I put the AIS on when we tow the camper longer distances.

I would focus on the intercooler efficiency more than the air intake. You can draw all the outside air into the intake just to have it compressed by the turbo and heated to 150+ degrees. If running a chip/tune that yields running higher boost the stock intercooler will not be able to reduce the manifold air temps like it can in a stock setup.
If your focus is on colder intake temps and you are not running a stock setup, I would do some research on intercooler upgrades. This will yield much bigger gains than the air intake alone.

I guess that depends on what your setup is and what you use the truck for. The stock intercooler is fine for up to @ 300ish HP but after that it looses it's efficiency.
what is your setup or planned setup?
do you have a scanner or OBDII reader that can monitor air intake & manifold temps? Most will, like TorquePro or Auto Enginuity.
The 6.0L intercooler is popular because of the low cost compared to some of the aftermaket options and will drop EGT's a good 50 degrees unloaded and 100 towing. But the aftermarket ones will double that.
I've been running Diesel Innovations (The big DIIC) in my F-250 for about 10 years and in the Excursion for @ 3 years. I don't have to worry about EGT's much at all. On my last data log 10 days ago with outside air temps at 97 degrees F I saw 98.6 F for air intake temps and 113F for manifold air temps at 20 PSI of boost with the 6637 air filter. Here is the link to a couple of aftermarket options.......
You aren't going to like the $800-$1000 price and unless you are really hopped up tuning, turbo, fuel and turbo-wise, you aren't going to need it anyway.
I have the S&B with the zoo dad mod and foam between the fender and air box, and while on the highway, my IAT is within a few degrees of ambient. When I come to a stop, it shoots up at least 15-20 degrees. Here's a screen shot of a heat soaked, steady state, towing 10k up a 5-6% grade. IAT is 62* while ambient was probably high 50s. MAT was 118*. I think my 6.0 Trans cooler is erasing any benefits of a cold air intake by blocking too much air flow to the IC.
