I have the AEV snorkel so could keep the windshield lights - I use these lights much more regularly than any others given their higher location and beam pattern, so IMO your choice boils down to do u want windshield lights ?

"There is a low-pressure area created at the front edge of the hood when the vehicle is in motion, and we placed the central vent of the hood in a position to take advantage of this..... the placement of the center vent causes cooler outside air to be sucked through the radiator and up through the hood to fill in the low-pressure area."
A Wranglers' engine bay gets quite hot. Wouldn't it be better for the battery (to name just one example), to be cooler?
I'd expect a 'cooling hood' to cool the engine bay, and not just the radiator.
The side vents, too, are placed forward, to cool the radiator only.
If they were located further back, they would have let hot air out from where it's the hottest.
When the AEV snorkel is used, one of the two side vents is plugged, countering their own design.
But that's not all. According to AEV, this 'cooling hood' works only when the Jeep is in motion. This means that the hood becomes more and more efficient the faster the speed is.
We need it the other way around... offroading is typically slower than road speeds.
When we need cooling the most -- crawling in hot weather -- this hood does nothing.
I, therefore, regard this hood as useless.
Also… do we want indentations, which collect mud or dirt, in the hardtop or the fenders?
Why have it on the hood?
Yes, water or mud is splashed under the engine. This is no reason to add yet more water or mud from above.

The lil bit coming in from the top won't make a difference, if he likes the hood he should get it, if I had the extra money I'd buy one too but I'm fine with my factory hood and saving for more suspension parts instead of a hood.

I think I spent $15 on extending my breathers. I did a write-up about it.

But like I said, I will take your opinion and continue to research on it because it definitely is valid

The AEV website also says:

When I'm in my jeep I'm usually in motion but I see your point.
I think what aev is saying is not that they are cooling the rad only (though this is quite important) but it is saying it is sucking cold air through the rad to the already low pressure area that was designed to keep the wrangler cool...that's just how I read that but if I'm wrong hey I'm wrong.
And I understand your point about the snorkel using a vent but isn't the AEV snorkel going to let some cold air in anyways?
