It has been said that the spark plug was one of the most patented items in the United States, second only to the mouse trap. With hundreds of designs and thousands of variations, one could spend a lifetime collecting and never find them all. Even after a lifetime of collecting, new and previously unknown examples continue to be discovered by collectors around the world. It truly is a hobby with no limits.
