They do absolutely nothing for performance, this debate was put to bed years ago.
Platinum and Iridium plugs were developed to increase plug service life, to keep pace with advances in engine materials and oil tech, pushing service intervals of cars to 20k plus mileages. They do that by being harder, they resist wear from spark erosion much better than nickel alloy which is what standard or what's referred to as copper core. But copper core perform better than either Platinum or Iridium they just don't last as long and as they fail the start to misfire more. Plugs with dual or multi electrodes were developed for the same reasons, i.e. service life, Platinum and Iridium perform better, the latter being better the the former of the two.
Yes they will last longer no they won't increase throttle response, its placebo effect. All that is happening is the old plugs were starting to breakdown (misfiring) changing them with standard plus will give you the same result.
