The only hose connected to the airbox is the air pump supply.

No. That approx 3/8ths inch nipple goes nowhere. Just gets capped off.

I don't know of this nipple Hailers mentioned. It's been years since I saw a stock airbox. There's only one hose connected to the intake duct that I know of, and that's for the BAC and AWS valves.

Post pics so we now what you're referring to.

No, it just means that unfiltered air is being used for the secondary air injection system (air into exhaust to lower emissions).

Any hose of the right diameter will work, but the bend might be a bit sharp causing it to kink. The factory hose is pre-formed. You could get it from Mazda (p/n N326-20-751) or look for a used one.
