Description

Autolite® Xtreme SportTM spark plugs are designed with an iridium-enhanced fine-wire center electrode to provide better ignitability*, faster fuel combustion, and a more focused ignition. Upgrading to iridium will equip your small engine equipment with greater ignitability and 21% less hydrocarbon emissions than standard plugs, resulting in better fuel efficiency and horsepower.
