When the parts come from Sparkplugs.com, they’re individually packaged as such.
The NGK coils also have their own sealed packaging.
Unlike with a factory coil, each NGK coil comes with a metal barrier, which probably serves as a little insulation from the cylinder head’s heat. You'll notice another one of these metal pieces inside the sparkplug galley.
The factory Bosch plugs are four-pronged, and don’t require any gapping. They run about $15 each from Sparkplugs.com.
If you need gloves, Sparkplugs.com has a nice set of mechanics gloves, too, which are especially ideal for heavy-duty automotive jobs.
