I'm not completely sure I follow, but remember you ARE getting cold air already from the ram air scoops on the intake that reach over the radiator to get cold air at the front of the car. My intuition tells me that increasing the distance of the intake piping to the air filter might create problems with air velocity, resistance and ultimately, the MAF sensor readings.
