When I installed my stepped intercooler I cut the bottom half of the shutters off and kept the top part intact and I can confirm that the car went from taking 2-3 minutes to warm up to now it taking 5-6 minutes to get up to operating speed.The shutters are for faster warmup and extreme cold operation.
Not really a bad thing though, The open area in front at the bottom keeps the IC cold, and the shutters up top at the radiator help it warm up, so it's a trade off I'm willing to accept being as winter is only 4 months long here in southern PA.
