Autolite Iridium XP spark plugs are engineered with an iridium-enhanced fine-wire and a proprietary, platinum ground electrode, to increase durability*, while its tapered ground wire maximizes engine efficiency, delivering improved engine performance, fuel efficiency, acceleration, and ignitability.

Features and Benefits:

  • Designed with a nickel-plated shell that is corrosion resistant to provide increased durability for extended periods.
  • Engineered with an Iridium-enhanced center electrode and fine-wire design that increases ignitability and provides a more focused ignition for improved engine performance.
  • Includes a lifetime limited warranty that guarantees optimum performance equal to OE designed plugs.
  • Its high alumina multi-rib ceramic insulator provides thermal conductivity and superior insulation for increased strength while preventing flash-over.
  • Its proprietary platinum ground electrode provides increased durability* and resistance to wear, extending the life of the plug.
  • The tapered ground wire improves engine ignitability.
