No metal tubes, metal = heat soak = increased temp of incoming air charge = no good.
Feed it cold air. I would rahter have a modded factory airbox with a good filter then I would some CAI sucking warm air from under the hood. So even when I do use a cone filter under the hood I take steps to make sure it is shielded from the heat of the exhaust/engine and also the turbulence from the engine driven fan. Use ducting to feed cold air from behind grill/headlight/fender to the filter. Also a way for heat to escape really helps drop underhood temps. The colder the air the more power you will make. However as stated above you may sacrifice some MPG a hot engine is an efficient engine (some of these newer cars/trucks run at like 240 water/trans temps)
Use a good filter, like the Amsoil/Injen blue dry filters, they are great
If you have an older engine with a metal upper intake you would see far better performance gains from a simple intake spacer then you will from a CAI, putting phenolic material spacer between the lower intake and upper intake will keep the upper intake much cooler = lower intake air temp = more powerÂ
Breathing mods are VERY beneficial at high elevations like Colorado rocky mountains, otherwise the CAI is basically looks cool, unless you do it right and actually decrease the temp of your incoming air.
You will always only be as good as your smallest bottleneck, usually somewhere in the exhaust manifolds on our RBV
