Scroll down through the thread and see how the guy wraped heat insulator on the air intake. Sounds the IAT did go low.
Has anyone done this on stock or CAI ? Is it effective ?

If your looking for a cold intake, you should take a page from the "Old Farts Motorhead Handbook". Cut out an intake gasket from 1/4 phenolic plastic and sandwich it between two conventional intake gaskets. Poor man's thermal barrier. (engine heat can't reach the intake by radiating thru the aluminum.)
A sandwich of alternating gaskets of Aluminum sheet, and Conventional Gasket Material is even more effective, and more torque(crush) tolerant too!

The engine bay temps in summer are hot enough to heat any aluminum intake (just reach in and grab your aem after a long drive in the summer). The thermal wrap ideally helps to keep this from happening. But with the velocity of the intake charge, the temperature from the air passing up a heated intake tube is probably not as affected as the charge after it enters the IM.

yeah its strange sometimes it does that. but do try again. It did not ask me to login now.

True. but the length of the tube as compared to the distance the air travels in the IM is pretty long so the air is more likely to be affected by hot temperatures in the tube than the IM. And the MAF, IAT, IAC are all kinda before(?) the IM so the amount and temperature of the flow in the tube should have some effect on the way the ECU makes its calls.
Not arguing just thinking out loud...

 

heat insulator: yes it will work

but another thing that would keep the heat from your engine to getting to your intake would be a heat guard, which im not sure if there make for hondas...but i know ive seen them on numerous BMWs, it may be called heat shield, something along those lines, but all it does is bolt on around your intake pretty much

 

These are what I found at Home Depot -
Frost King duct insulation (self adhesive, easy to use just like tape, foil and vinyl foam R-Value=3)

Duct Sleeve (fiber glass R-Value=6)

Reflectix (two bubbled aluminium foils with air space in between R-Value=4-6? depends on installation?)

The frost king seems to be the most convenient to use. Duct sleeve most effective but not user-friendly, quirky to use(installation etc..)
Not sure about the reflectix - seems more effective for radiation heat rather conduction/convection type heat.

I think I am going to try the frost king. I can always add another layer if I feel its not insulating enough.

Wondering if it would be a good idea to apply insulating material on other parts that could use some insulation from the engine heat like A/C lines, the 'cool' coolant line going to the bottom of the radiator etc..
