NGK claims 2X the life of Iridium and better oxidation resistance, which I'll buy. There are some ruthenium alloys that are off the chart for both melting point and corrosion resistance. NGK also claims "high ignitability", which I'm not sure I buy. The way Nissans stubbornly refuse to fire when flooded, maybe they're more resistant to flooding and that would be nice. That one goes in the "we'll see" column. I think the bottom line is, if you're ride has insanely hard-to-change plugs then they're probably worth the difference. Otherwise, Iridiums are already good for 100K.
