1) The stock (original equipment) air intake is a cold air intake. I haven't taken apart an E70 intake, but this was true on every other BMW I owned, so I suspect it is true on the E70 as well.
2) The restriction in the stock intake is negligible.
3) Aftermarket CAIs commonly take their air, paradoxically, from under the hood. Those that do are in fact hot air intakes, despite the marketing labels attached to them.
