any spark plug will work... the only reason makers tell you to use platinum or iridium on some engines, it's simply to warrant a longer service interval... of course, high power ignition systems/coils will wear out the weaker metals faster, so an iridium plug will probably last longer than a platinum one, and both of these will outlast copper...
