Some protection for the fogs, airflow and yes.....does help to keep dirt out.

The reason I asked was this. I have seen them advertised at different places and I can understand the principle of letting cool air into the engine bay(along with dust and dirt). I just didn't feel like paying for them, so yesterday I swapped out my stainless fog light screens for some black powdercoated ones and while I had it open, I took a 1" hole bit and drilled 4 holes across the surround on both sides. Maybe it will help keep it cooler and allow a little clean air in there, who knows, only time will tell.

As mentioned, the Vararam requires it due to it's design, however if it's good enough for the Z06, I'm sure there is some science behind the additional cool airflow coming in.
I just wouldn't buy into any manufacturer's claim of any significant HP increase. Like the Hood Seal!

I have Three 1" holes in each side the reason for them is to let cooler air in to the filters. I do know it looks badass and I get compliments at from vette owners all the time. I have a twin K&N filter setup and the only way for it to get air is sucking from the hot engine compartment, the holes feed in fresh cooler air. And I have driven in rain at 75mph for miles with no problems, Unlike the ones that cut the rad cover and suck water in heavy rain and high speed.
