Autolite Spark Plugs — Proven Performance at Every Price Point

Autolite has manufactured spark plugs in the United States since 1911 and remains one of the best-value ignition brands on the market. Known for delivering OE-quality performance at accessible prices, Autolite plugs are a popular choice for mechanics and DIY enthusiasts who want reliable ignition without paying a premium. Their product line covers a wide range of domestic and import vehicles across copper, platinum, and iridium formulations.
