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.
Features and Benefits:
- Engineered with an iridium-enhanced fine-wire center electrode that delivers greater ignitability over standard non-fine-wire spark plug.
- Its high alumina multi-rib ceramic insulator provides thermal conductivity and superior insulation for increased strength.
- The tapered ground electrode provides improved ignitability for more efficient and smoother starts.
