sort of
in my case i think it might look like this
in this pic you see the actual open grill so the open area of the top grill is much smaller than it visually looks, therefore if the "shield" would stand only a short distance before the grill, the resulting opening would be about the same as the open grill. you also see that the totall grill opening on my car is really not that big so i have to be carefull as the car gets hot pretty fast
