Do grille overlays seriously restrict airflow?

I want to get the black billet grille overlay sold by American Muscle among other places.

But I just realized, since it doesn't remove the stock grille and goes right over it, can it negatively affect airflow into the engine bay/radiator to a significant (power draining) degree? D:

on my 2006 GT, i installed billet grills upper and lower, i doubt they restricted air flow at all, may have re-directed it a bit though.

definately a nice mod to do, easy and quick
Runs no different temp wise. Its a pita to put the bottom one in if you have a intercooler but it protects it and looks great :bigthumbsup
I don't think they would affect cooling at all.
As previously said, I don't think you have anything to worry about. :bigthumbsup
Is the stock grille noticable underneath the overlay?
Only if you are looking for it, and cooling isn't an issue. Check out the overlay in my gallery.

So how does the overlay apply? Snap in ect?
It clips to the front of the stock grill, and secures w/ screws on the back...easy!

i dont know if i could do an overlay. I would always see the honeycomb underneath and be bothered by it. I wish they had a grill that was black that had an area for the foglights
SAME. I had the exact same thought. I'm hoping I won't OCD over it too much and end up taking it off. I wish they had that type of grille too.

we should make one lol. :laugh: i was thinking of buying an overlay and putting it on and cutting out the honeycomb just enough that I could keep the the mustang on there and hold the lights in place but get rid of the honeycomb. But I would have to buy the overlay and see if it would work. Plus my light extenstions might mess up the little sides too. :nogrinner
I did the next best thing... Just put my stock fog lights behind my black billet grille. Here's some pictures...

Before the emblem...

I thought about doing something like that, but I'm too attached to having my foglights exposed, I recently put blue tints on them.

what does that setup look like with the foglights turned on, though? I'm curious to see :U
