Autolite has been a staple of American garages for generations. Now part of the Fram Group, Autolite remains one of the most accessible and value-driven spark plug brands available. Here's when Autolite makes sense.
Autolite Copper Core
Autolite's standard copper plug is a solid workhorse for older vehicles and high-volume fleet applications. 20,000–30,000 mile service life. Widely available and priced competitively. Good for older domestic vehicles where iridium longevity isn't needed.
Autolite Platinum
Platinum-tipped center electrode for 60,000-mile service intervals. A practical upgrade from copper that fits most domestic vehicle applications at a budget-friendly price.
Autolite Double Platinum
Double platinum (both center and ground electrodes) provides up to 100,000-mile service in distributor-type ignition systems. The bilateral platinum protection prevents uneven wear in waste-spark systems.
Autolite XP Iridium
Autolite's iridium offering. Fine iridium center electrode with a nickel-plated ground electrode. Competitive with NGK Iridium IX in terms of performance, often at a slightly lower price point. A good value iridium choice for domestic vehicle applications.
Best Applications for Autolite
Autolite is an excellent choice for older American vehicles (pre-2010), classic car restorations, and budget-conscious maintenance on high-mileage domestic vehicles.
