Nice! I figured a smoke test may be useful, but if you have an even better idea I'd love to see it.
The smoke test with my old fog machine is the idea I had actually.

Adding vents like this should reduce IAT, but like some have mentioned, introduces a new problem with allowing water to collect in those channels meant to dissipate heat. There is some built in drainage, but not sure how much it’s actually meant from a top-down water scenario.
It shouldn't have any effect on Intake Air Temperatures, even with an exposed filter element design, but will help reduce the overall Under-Hood Air Temperatures.

The vent plugs certainly aren't watertight, and the axle-back sides of the clamshell hood have adequate drainage holes. There's also a "sticky-looking" anti-corrosion coating along the inside edges of the hood structure itself, so no need to worry about drainage or potential corrosion.

I believe that the IAT tends to be affected heavily by heat soak from under hood temps. The two are highly correlative.
Forgive me, I was only thinking about the air temperatures at the mouth of the airbox inlet itself, in the stock location, while the vehicle is in motion.

Just a note for folks. Since this isn't a clear passthrough from the top of the hood to below the hood, things can get stuck in there.

I remember my Evo X had a hood vents, it got some tree seeds or something in the hood. I never could tell a great way to get them out. So every time I opened the hood, you heard things rolling around.

Are you sure it wasn't a 10mm socket?

I really want these vents but you’re describing the automotive equivalent of getting a pick stuck in a guitar… nothing on Earth is more frustrating.

Maybe, clearly i didn't try very hard.
Short story time: I lost a half dollar down the door panel of my grand dad's car when I was a child. I was holding it against the window and rolling the window down. Rubber popped up over the coin and down it went. He had to take the door panel off the retrieve it.

haha. We had a cell phone slide down an air vent in a 90s Dodge Caravan. Somehow someone's arm was skinny enough to reach it. Almost couldn't get it.

Hence i would ONLY go for a vent with a mesh grill to keep leaves/stones out
