Alright, here they come:

California has special requirements for gasoline, which makes it more expensive because of less availability. We also use different blends for winter vs. summer. That's what I was referring to when I said "grade". Never thought or meant octane, you did.

Here is the article on cold air intakes on Wikipedia (I really don't know what will convince you because you seem so arrogant as to believe that you and only you know the truth). The first sentence is:

Standard air intake systems tend to be very restrictive, in order to eliminate engine noise.

The whole article: http://en.wikipedia.org/wiki/Cold_air_intake

I remember seeing a video interview with an engineering expert, when I was shopping for my intake and he was saying the same thing. That's the main reason, noise. I did not come up with this in my dreams. Unfortunately, I can't find the link to the video right now, but I will eventually and will post it here, so you can be enlightened as well.
