heatsoak is overrated, the entire engine is heatsoaked for that matter. you will not see a difference between plastic and metal. the couple feet of tube won't affect the air temp rushing into the tb. u would need a exterior intake and driving 160mph+ to actually benefit from "cold air" intake.

6.1 intakes are all metal and when guy's race with them they heat soak. There is a reason they literally put bags of ice on their intake to cool it off.

I'm totally guessing at the max flow rate but let's say 600 cfm. That's 10 cubic feet of air per second, or 17280 cubic inches per second. A 3-inch diameter intake 3 feet long is 254 cubic inches, meaning the engine flows the volume of the intake tube 68 times per second. I'm no good at calculating velocity but I promise that's some fast-moving air. It isn't hanging around long enough to pick up any heat.
Even at half that figure, heat soak due to the pipe material isn't an issue. Air is an insulator. That's why it requires a radiator-type setup with fins to dissipate heat. It could flow though a pipe that's 400 degrees and it wouldn't pick up any of its heat when it's moving that fast.
You can heat soak the temp sensor at idle, and the incoming air under the hood is hotter than ambient, but once you start moving that problem is gone. It'll take a few more seconds for the temp sensor to read properly after that.
Having said all that, I don't see why anyone makes them out of metal when plastic is easier, cheaper, and works just as well. I picked mine because it was cheapest and it's been fine for almost 5 years now. It never did mount "properly" but I don't care because it's just a pipe with a filter on it, and a heat shield. I would never give anyone hundreds of dollars for an intake.

Right, Ill agree with all that but your actual air temps mean nothing when the IAT says it is something else and gives those reading to the PCM. Thats why we use a lower stat (180*) and a powerwire which tricks the PCM be giving it false temps of 22* less than what they actually are to add the "benefit" of a CAI.
