You do not have to do what the dealer says. If you refuse the spark plug change he will have to still honor the warranty. He is just trying to make some bucks off you. You only need to do the maintenance as specified by the manual. Changing spark plugs at 24k will not give you any performance boost. For that matter, no spark plug will give you a performance boost over the stock Iridiums.
