I just want to keep this thread alive.

Still wondering about the 1 intake vs. 2 intake question. It seems like 2 intakes would allow an easier flow of air, especially as the filter gets dirtier, I would assume that would increasingly hinder the flow of air. I don't think I'd want to clean my filters every other week.

Next question is how important is air turbulence? A smooth round pipe with a mimimum of bends seems like it would allow a smoother air flow than just adding a filter to the stock setup with the whatever you want to call it plastic hood where the stock filters go. How relevant is air flow?

Last is just a couple of observations. First, I cleaned my filters after around 7k miles and what a difference! I won't let it go that long again. Next is after cleaning the filters, I checked under the hood a few days later and found one filter sitting on the bottom of the engine compartment. Don't know how long I drove without a filter, but that stinks. Got to be more careful.
