New Hondas are delivered with Iridium plugs these days. NGK or Denso
Iridium plugs would be my first choice, platinums second choice and
conventional third. The real difference is how long they will last.
Assuming no plug fouling from combustion problems (mixture, oil fouling)
then the Iridiums can supposedly do 100,000 miles. I changed the
originals on our '03 Accord at 50,000 miles simply to be cautious and
they were still in very good condition. Of course I put Iridium plugs
back in and will change 'em again at 100,000 miles just to be on the
safe side.

Just stay away from the Bosch Platinums. They use a tiny center
electrode which some cars don't seem to get along well with.
