Hello,
mowgli - If you check under the hood, at least under mine, it specifies ZFR5F-11 1.1MM no adjustment needed. As far as NKG vs. Denso goes, manual says NGK...I'd go with that. And as long as they're packaged correctly before shipping, they should not dammage. They're always shipped to stores without dammage, should be fine. Maybe check with the vendor as to how they'll ship.
wojeda/jeepney_driver - The 100K miles thing is a "definitely check me by then" time frame because they will guaranteed not last past that. There's always a possibility they won't even last past that. Never hurts to check once in a while for deposits/wear and replace when necessary - just like many other car parts. If it 'aint broke, don't fix it.
