My cone filter is right behind the driver's headlight. About 7 years ago I got to wondering about how hot the air was that it was being taken in. I rigged up a thermocouple right at the cone. As long as the car is moving at about 20 mph or more, the intake temperature is within a couple of degrees of ambient. At highway speeds, it was ambient. When the car is stopped, the temperature rises sharply but falls like a stone to near ambient as soon as the car gets going.

If your air intake is right behind the intercooler, that would not be good.
