    The Autolite Xtreme Sport® Spark Plug features a platinum finewire tip that helps with easy starting, reduces fouling of the spark plug, and ensures longer performance.

    Designed with iridium-enhanced 0.6mm finewire for improved ignitability, faster fuel combustion and a more focused ignition versus standard plugs. They also provide up to 26 percent quicker starts compared to that of standard plugs and as much as 21 percent less hydrocarbon emissions than standard plugs, which promotes better fuel efficiency and horsepower.
