    The history of the company began in 1911 when two small companies started manufacturing buggy lamps. By the 1930s, the company became a thriving automotive parts manufacturer. In 1935, Royce G. Martin, President of the Electric Autolite Company, equipped and staffed a lab to develop a spark plug. Robert Twells, a ceramic engineer, led the project constantly researching ceramic insulator technology.

    It only took a few months before the Electric Autolite Company had a spark plug available for distribution. In 1936, the first Autolite spark plug was introduced to the market and had instant success as a reliable and durable product. As a result, the company began to supply spark plugs and other ignition parts to well-known automotive leaders such as Chrysler, Studebaker, Packard and Willys, etc.

    Autolite developed and manufactured many innovative products that set new standards in the spark plug industry. The innovations of the company include but are not limited to Power Tip Spark Plug, Platinum Spark Plug for Ford O.E., Suppressor Spark Plug, and High Thread Spark Plug for Ford Triton Engine with 3 valve design (released O.E. in 2004). Thanks to its strong devotion to perfection, Autolite became a NASCAR Performance Partner.

    3 Years Without Problems
    These spark plugs are 3 years old with over 30K and my vehicle starts as fast as the day I put them in. It takes more then 2 hours to replace the plugs on my Mercury Cougar, so I want to do it only when necessary.
