- Autolite Xtreme Sport Spark Plugs are engineered to meet or exceed OE designs and withstand the extreme operating temperatures experienced during a powersports engine's combustion. Autolite Xtreme Sport Spark Plugs were designed with iridium-enhanced 0.6mm finewire design for improved ignitability, faster fuel combustion and a more focused ignition versus standard plugs. Autolite Xtreme Sport Spark Plugs 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. Autolite Xtreme Sport Spark Plugs feature a platinum finewire tip that helps with easy starting, reduces fouling of the spark plug, and ensures longer performance.
