Spark plug tech hasn't changed very much since the dawn of internal combustion due to one main, undeniable factor. A normal spark plug is the most efficient and refined design that leaves very little room for improvement. It is simple yet effective. To improve upon a normal spark plug would be similar to reinventing the wheel. Spark plugs will be the same until internal combustion is dead and gone. Getting it wrong is easy, just ask Bosch and their crappy platinum plugs.
