Stitt was originally founded in Ohio in 1916 as the LaFrench Power Spark Plug Company. In 1918 the company was renamed Stitt Ignition Company in honor of their first chief engineer, Benton Stitt. By 1953, Stitt was supplying it's multiple electrode, long life spark plug to stationary gas engine manufacturers for original equipment installation. Stitt found itself in a world wide market for specialized spark plugs designed for use mostly in large stationary industrial engines fueled by natural gas.

Texas was where most big gas engines were being used for the production and transmission of oil and natural gas. A major part of the company's business was located in Texas, so Stitt moved its operations to the Lone Star State in 1971. The company began working with the major heavy-duty diesel engine manufacturers in Europe as well. They developed programs to convert some of their products to spark-ignited gas engines as pipelines made natural gas more available. The success of these programs resulted in Stitt supplying its specialized spark plugs as original equipment to major manufacturers of gas engines.

Today's Stitt Spark Plug Co. is one of the oldest continuously active spark plug manufacturers in the world and continues to improve its product line with innovative technologies.
