Autolite Xtreme Sport Iridium Spark Plug Fits select: 1975-1987 BUICK REGAL, 1975-1985 PONTIAC FIREBIRD

<p> Autolite Xtreme Sport Spark Plugs are designed for powersport engines and feature a platinum finewire tip that helps with easy starting, reduces fouling of the spark plug, and ensures longer performance. Xtreme Sport spark plugs are engineered to meet or exceed OE designs and withstand the extreme operating temperatures experienced during a powersports engine combustion. They were designed with iridium-enhanced 0.6mm finewire design 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.</p>
