The Humble Spark Plug…


By David G. Firestone

So in planning my article for last week, I got to thinking…spark plugs were the most common race-used memorabilia item for many years. It’s pretty easy to see why. Spark plugs are the most commonly changed part, they are one of the cheapest as well. So once the spark plug has expired, instead of throwing out, you sell it to a fan. You get some money, they get a treasured item.

In 1970, Johnny Rutherford raced an Eagle chassis with an Offenhauser engine. He didn’t score a win, and had 3 DNS’s. These plugs came from that Offenhauser engine. They have been mounted to a wood display, with a small paper sign.rutherfordplugs-1 rutherfordplugs-2 rutherfordplugs-3
