Intercooler and pipe size?

I am nearing the point of needing to get a intercooler for layout on my car.
470 B motor with a F1X pump gas street car.
I was planning on running A2W on a boost switch and was wondering if a person can go too big on an intercooler.

I was going to run a cheap frozenboost type 12 and run 4" pipe.
Is it bad to run too big of pipe and intercooler?
