The oil change interval is the same at apprx 15K, or more likely when the computer triggers it.
15K plug change interval is what many practiced back in the early 90's when we ran high boost in our Mits turbo's.
It's no big deal though, unless you don't know how to change plugs.
You don't change coil packs with plugs, just the plugs. With the N20 you only have 4 plugs. You can get Bosch plugs for about $12-$13 each.
So that's $48 to $52 per change, which should be about once per year for most drivers. If you do more than 15K per year, then you're likely doing highway driving. For that I'd still do only once per year.
It shouldn't take a BMW tech any longer than an hour in billed time.
But, they probably charge between $80-$100 per hour, plus they'll probably charge about $15 per plug, $60. That's about $160 per year for a plug change.
The change interval seems way too short for such a modern engine.

I'd be shocked if the BMW dealers in the Boston area let us off the hook with just an hour's labor to change the plugs.
There's a difference between what it actually takes -- and what the dealers typically pork these normal maintenance services up to.
