yes and no. if you are driving an LT1 that can fry eggs on the cast iron intake manifold 3 hours after you shut the car off its one thing, but i wouldnt be too concerned about air temps between a plastic vs metal intake tubing.

This can be proven by watching intake air temperatures on the OBDII system.
