Hello all,
I searched the site and couldn’t find anything about the grill louvers. Does anyone know what these are for. I think I recall something about improving gas mileage but no description of how they work.
Is this something that is tailored to colder climates?

Active grill shutters. They have an electric motor that controls opening and closing. They are used to regulate engine temperature and they close on the highway to improve gas mileage.
