The thing is, spark plugs are what is known as a mature technology. They have not changed significantly in decades. There are numerous plugs touted as being miraculous, including iridium, split-fire, surface fire, and others. Platinum-tipped spark plugs were used in WWII airplane engines in an attempt to reduce lead fouling from the heavily-leaded aviation gasoline of the time. Unless you are replacing a plug which is so badly fouled or worn as to be misfiring, a new plug will make no measurable difference.
