Autolite has been around for over a hundred years. The company was founded in 1911 when two small businesses merged. They didn’t start making their famous spark plugs until 1935. Since then, the company’s spark plugs have become recognized as the industry standard. The company has supplied plugs to bigwigs like Chrysler, Packard and Willys, etc. At Deadbeat Customs, Autolite Spark plugs are the recommended replacement plugs for any Harley Davidson Motorcycle. We carry Autolite spark plugs for Harley Davidson Panheads, Shovelheads, Evo, and Twin Cam Engines.
