Well,I haven't noticed any dramatic increase at the strip,but it can't hurt. Did find a large bug splattered on the firewall one time,,so it must be getting some air in! You may want to have a way of sealing it up,in case of rainy weather. I don't drive mine in the wet,so no problem for me. But it is nice to see that it is open and functioning. I removed the honeycomb piece completely.Then you have to cut out the back area where the honeycomb insert was attached. Then cut out the old GT scoop area.You need to remove the hood pad and scoop to do this. You also need to make a center support piece to stabilize the scoop.
