I wonder if anyone has experimented with aerogel 5mm sheet as a gasket material faced with stainless foil and/or spray copper as a thermal conduction inhibitor stack? Here is a link to a patent contemplating aerogel gaskets as a key enabler of solid oxide fuel cells...

excerpt... "In many high temperature fuel cell systems such as the system (100) shown in FIG. 1, the housing (104) is made of stainless steel or other structural materials, and the fuel cell (102) includes ceramic or other materials. The interfaces (127 and 128) between the stainless steel housing and the ceramic fuel cell components are very difficult to maintain in high temperature conditions. However, it has been discovered that gaskets made of an aerogel can provide the desired seal between fuel cell system components.
... The aerogel gaskets (130 and 132) are preferably made of silicon based aerogels... Alternatively or additionally, the aerogels may be covered by a skin (e.g. a gas-impermeable skin) to reduce permeability prior to use in a high temperature fuel cell."

So, following this thought train, one could conceive of a system where suitably reflectively skinned and fitted aerogel gaskets could be installed to isolate non-pressurized parts from the engine's metallic heat paths. The throttle body and intakes are metal and thus highly efficient heat conductors - a bad thing. If this works, next, one could then try said gaskets in pressurized locations and if they worked, you would keep all parts in the intake train as cool as possible such that they would quickly and dramatically benefit from cool air washing through the CAI as soon as the car accelerated from rest.
