NGK Iridium IX Spark Plugs? Are these good plugs for the NSX?

I don't recommend for nor against Iridium spark plugs.

Most people on Supra forums running higher boost don't run Platinum spark plugs. Iridium is 6 times harder, 8 times stronger, and has a melting point 1200 degrees higher than platinum. A lot of Supercharged S2K owners also run Iridum spark plugs.

I think we should make the car out of Iridium instead of Aluminum. It sounds like the wonder metal of the millenium. 1200 deg higher melting point than platinum. That's got to put it to like at least absolute zero temp.:wink: I recommend champion copper core, and leaded petrol. That way you change $.50 plugs every 12,000 to 15,000 miles and don't worry about the cost.
