I specifically posted in h2 and h3 for forums as both vehicles have them and possibly out of the two groups someone might have tried it.

Why remove?

General Motors Air Curtain Technology

Air Curtains are a General Motors aerodynamics technology that provides improved aerodynamic performance (maximizes aerodynamic efficiency) by utilizing a specially-engineered tunnel at the front of the vehicle that manages airflow.

How It Works

The goal of air curtains is to reduce drag and improve aerodynamics by guiding air around the vehicle’s wheels, rather than into the wheelhouses. Aerodynamics play an important role in maximizing a vehicle’s fuel economy while at the same time reducing noise, vibration, and harshness (NVH) levels experienced by its driver and occupants.

GM’s implementation of the air curtain can vary from a design standpoint, but all scenarios generally involve an inlet or a series of inlets on the front fascia that allow air to enter, followed by specifically-engineered outlets that guide the air around the wheel.
