Integral part ignites fuel in internal-combustion engines


A spark plug fits into the cylinder of a gasoline-powered internal-combustion engine and produces the electric spark that ignites the mixture of gasoline and air.

“A spark plug is quite literally the spark that ignites the fuel that makes the piston go up and down,” says Bill Bond, founder of the Spark Plug Collectors of America. “And that makes the car go down the road. If you were to take the spark plugs out of your car, you’d basically have a boat anchor.”

In addition to new and vintage spark plugs, Joe Cook collects advertisements, promotional items and spark plug boxes.
