These cars came with single platinum plugs, meaning 1 of the 2 electrodes are platinum. Iridium plugs are similar, they have a platinum negative electrode and an iridium positive electrode for longer life. If you want something that is more likely to give you a better spark over OE, then run a double platinum (both electrodes are platinum). They are cheaper than iridium plugs, too.
