Slightly off post but related, I plan to get the inlet manifold on my "R" coated.
The PFC allows for monitoring of the air inlet temp and this suffers badly from heat soak when not moving. It takes a long time for the temps to drop again once you start moving. I confirmed by finding the manifold very hot to the touch (estimate ~ 70 C) when the air inlet temp temp is showing around 50 C.
The intercooler outlet pipe actually stays very near ambient temperature (from constant checking by touch) with only minimal driving, however, indicating that the intercooler is working quite efficiently.
It would therefore seem that with a decent intercooler, controlling heat soak from the inlet manifold is just as important (or more so) than having a cold air intake box.
