Description

The Autolite Iridium XP Spark Plug is Autolite's top-tier ignition product, backed by over 100 years of engineering experience and more than 11 billion plugs sold worldwide. The Iridium XP is designed and engineered in the USA, combining iridium finewire center electrode technology with patented platinum sidewire construction for focused, reliable ignition. The plug addresses the two main causes of spark plug wear: center electrode degradation and sidewire erosion. Conventional plugs gradually lose gap precision as their electrode surfaces break down, but the Iridium XP's advanced materials resist that breakdown, holding the factory-set gap with virtually no erosion over time. Consistent gap spacing translates directly to steady spark delivery, promoting reliable firing and smooth engine operation throughout the plug's service life.

Features

  • 0.6 mm Finewire Tip: Ultra-fine center electrode concentrates spark energy for enhanced ignitability
  • Double Iridium-Enhanced Alloy: Center electrode composition delivers improved durability and wear resistance
  • Patented V-Trimmed Sidewire: Platinum electrode shape minimizes erosion for long-lasting gap accuracy
  • OE-Equivalent Design: Fits original equipment specifications for easy, modification-free plug replacement
  • Autolite Part XP5364: Reference this number for accurate cross-referencing and ordering
