noticed white (see pic) and also redfire also come in body color while others seem to come in black...em i missing something? also i dont believe this has anything to do with stripe upgrade,as cars i noticed this on,dont have any stripes...

 

Older cars didn't have the 'new' insert.

The black portion is actually an insert that covers the outer 2 holes with 'filled in' honeycomb.

 

They toyed with painting the vanes black and then just came out with the insert for production.

 

I was told by a Team Mustang individual at the Ford Racing Innovation Drive in Detroit that the insert is intended to restrict air flow. It has solid portions just like the grill. I got the impression that unnecessary air flow through the front of the car can increase drag and effect fuel economy.

That's why in NASCAR they duct tape the front of the car untill they get just enough airflow for the motor to run cool enough.

 

I think we all learned something here and can now put this item to bed for a long nap.
