All cold air intakes are helper mods. You may notice somewhere between 5-7 hp but they really shine when you add a free flowing muffler, programmer and things like a cam and larger tb. But that is nice work.
I don't think you get any more air with a two filter setup, you are still going into the same diameter TB, but my guess is you'll see longer life out of the filters and longer intervals between needing to clean them, as each one is probably taking in proportionately less air than a single filter.
