Introducing the new Autolite XP Xtreme Performance Spark Plugs. With an iridium-enhanced, .6 mm finewire design and patented platinum sidewire technology, these plugs provide more focused ignition for better overall ignitability and improved durability.
Independent lab tests prove that Autolite XP Xtreme™ Performance Spark Plugs provide better overall ignitability and durability than many other premium spark plugs. By increasing the size of the flame kernel, you get a 21 percent bigger flame compared to that of standard plugs. The new Autolite plugs ignite more gas and air mixture inside the cylinders to deliver better overall performance. The ignition is also more focused, which provides better and faster fuel combustion, optimizing the vehicles spark plug performance.
