The intercooler will soak up heat when it's not being cooled...so the initial air charge will not be cool until the intercooler is back to ambient temp. Good example is the IAT sensor located in the airflow. Sometimes it may take a few minutes before the air temp reading is back to temp after heat-soaking under the hood.
I have found that Gorilla tape will let go under adverse conditions like heat (sun/engine), pelted by dirt/sand particles aided by wind. The minute particles work their way under the tape and slowly pry the tape off. Since tape is not self recoverable...it will eventually lose to the adverse environment.
One of the key things to consider is how much force the louvered system can withstand without bending/deflecting.
