The one that looks normal can be suspect too.

The white insulator ceramic can have a small hairline fracture , separate and intermittently cover the conductor tip.
Unless you inspect it closely and or tap on the plug in an inverted position to simulate combustion pressure you might miss it. The defect rarely is present under normal load and usually only presents itself under heavy load at full or open throttle conditions .
It is recommended to closely inspect spark plugs before installation.
