There have been several tests done with "Air" "Temp" and "Intake Tubes" (metal vs. plastic) and basicly,... The Air isnt in the tube long enough to change temps so as far as Insulating your intake tube for other than looks might be a waste of time and money. I have a True Flow intake and I believe there are test results on their website somewhere that might explain it better to you.USMC5593 said:I am in the same boat, I was thinking about doing the same thing for my 07 4.7L ram.
but mine has more bends than the one pictured. I am trying to decide between aluminum exhaust tubing or PVC pipe and maybe insulation over it. do you know what the inlet size is on the AEM dry flow 360 degree filter?.
