Not sure how much the extra frontal area helps as it doesn't get direct airflow - AA did the same thing, but provided a shroud to direct air into the portion that is behind the bumper.
I think you can't go wrong with either though!

The entire helix is fully exposed above the plastic cowl to direct airflow! The helix comes to the top of the center grill below the bumper.
