1. You could take our word for it,How do I know if my 2016 Chrysler 200s (2.4L) has active shutters ?
2. You could lay face down on the hood with your arms and legs spread eagle holding on to both fenders, rear end toward the windshield, with your head low enough to see in the bottom grill, and tell your best buddy to punch it til it says about 70 mph. Watch the flappers in all of their glory. This takes a while with the 4 banger.
