About Us

The Autolite story began in 1911 when two small companies started producing buggy lamps, becoming a thriving automotive parts manufacturer by the 1930s. But its history as a spark plug manufacturer began in 1935 when Royce G. Martin, President of the Electric Autolite Company, equipped and staffed a lab to develop the first Autolite spark plug. Leading the project was Robert Twells, a ceramic engineer, who eagerly researched current patents and ceramic insulator technology.

With a handful of new draftsman and staff members, it only took a few months before the Electric Autolite Company had a spark plug available for distribution. Autolite had instant success, as the brand supplied spark plugs and other ignition parts to well-known automotive leaders including Chrysler, Studebaker, Packard and Willys.

    5 Stars
    Looks good so far.
    The spark plugs look solid, clean, and ready for installation. The measured gap for each spark plug is 0.042, 0.043, 0.043, and 0.044, the advertised gap was supposed to be 0.044" so not too far off I suppose. They will go on a 2009 Mitsubishi Galant 2.4L.The only concern I had was when I received the package that the 4-pack box was opened and missing a piece of the corner (not damaged from shipping) and it appeared as if someone took a quick look at one of the plugs and accidentally ripped a piece out of the box but nothing serious, the individual four boxes were intact otherwise other than one of the individual boxes looked like it was opened once.I tried to be artistic with the photo, I hope you enjoy it.I have not installed these plugs yet but if I have any issues I will come back and edit my review otherwise I will leave a 5-star for now as I have used this brand in my other two vehicles without issues so far.
