a few people have said to me recently that a standard airbox will be better for my car i.e power figure, cos the cone filter only sucks in hot air.

on a N/A car i would tend to agree, but surely on my car, with pro-alloy cooler, by the time that 'slightly' hotter air is compressed, then cooled by the I/C it will enter the engine at the same or very similar temps.

so, what i am saying is the standard airbox will probably draw cooler air into the turbo, but the effects of the intercooler will overcome any shortcomings of a cone filter,

OR is it more linear like;

airbox temps 40 degrees C ---> I/C inlet 75 degrees C --->I/C outlet 40 degree C = 35 DegreeS drop

so ;

cone filter temps 45 degrees C ---> I/C inlet 80 degrees C ---> I/C outlet 45 degrees C = 35 degrees drop but with 5 degrees C increase throughout
( ignore temps , i have no idea what they would be )

i personally reckon the I/C WILL overcome any slight change and will keep temps to roughly the same level
