Dual Snorkel is better because it retrieves colder air from underneath the front of the hood rather than sucking warm air that rises from the hot engine.
Unless you have a ram air hood and want to configure some weird Ram air setup with the Open Element, the Snorkel is better because of the Colder, Dense Air that is drawn from the front of the car.
I think the colder air intake would make the engine less prone to detonation too, so you could get away with lower octane fuel. I know my car would ping even with 91 octane in it when I had the air cleaner on the normal way (it has no cai stock), then when it was flipped over so that its basically an open element, which bypasses the thermac valve it would run fine with 89 in it. This is with a stock 87 LG4. I imagine the dual snorkel setup would give even colder air which would help even more. Once I get my egr valve fixed i should be able to run 87 octane.

Flipping the air cleaner lid almost always slows the car down. Of course, all the "cool" noise recalibrates the young inexperienced impressionable driver's butt dyno, so he thinks it mnust be faster since it's louder, even though it is in fact slower, maybe significantly slower.
Look at how the air cleaner lid is made. Notice that it has a tall place in the center, that rises above the surface where the filter media mates to it. When you flip it upside down, that tall center is then below the air filter, sticking down toward the air horn; this makes a very narrow place that the air has to squeeze through to get into the carb. So you get a triple whammy of negatives from doing that: (1) hot air instead of cold; (2) restriction above the carb; (3) extra unnecessary and unwelcome high-school-kid monkey-spank noise.

Yes.... ask me how I know this... I did it too, when I was even more ignorant than I am now, if you can believe that such a thing could be possible...
Oh to be young again! If I only knew now as much I thought I knew then! Youth is wasted on the young, they are too inexperienced to appreciate it.

Well mine is only a single snorkel with no cold air tube stock so it is putting in colder air by putting the lid on upside down, and it is giving me noticeable more power with it flipped, it's not just the noise. I just realized a minute ago, when I said I just flipped the lid thats not completely true. I'm using a chrome air cleaner lid flipped upside down on top of the stock air cleaner and filter, this one actually doesn't have much of a rise in the center so it probably doesn't block much flow.

Do exhaust leaks make you faster too?

I'm sure we've all turned our air filters up side down in our younger years. Supreme Member

Hmmmm.... go get a monkey, and spank it, real fast like.
That's what kind of noise it is.
Remember though, if you keep doing it you'll go blind; so if you suddenly find you need glasses, quit it right away.

Guess I need to trade in my nice chrome open air filter with a paper element to a dual snorkel. Aren't those a little hard to find and can these be bought new still? Supreme Member

Dual snorkel
It gives cold dense air, the open element supplies hot thin air
