Autolite, often known as Auto-Lite, is an American manufacturer of spark plugs and ignition wire sets. Products from Autolite are available in the United States, Canada, Mexico, and Australia. Until 2011, the Autolite brand, along with FRAM and Prestone, was part of Honeywell's automotive Consumer Products Group. It has since been produced and sold by FRAM Group, a subsidiary of Auckland, New Zealand-based investment firm Rank Group. Since April 2000, Autolite has been the official spark plug of NASCAR.
