I read on forums that a fair amount of '19 Zroners are worried about the plastic grates and are adding metal screen overlays to them.

Keep in mind that each of those plastic grates is behind two heat exchangers. The front exchanger is for the supercharger charge air cooler and the rear exchanger is an auxiliary coolant radiator.

Whatever extra protection you add, you want to make sure it's coarse enough so that it will not restrict airflow through those heat exchangers.
