Description:
The Autolite AP985 Platinum Spark Plug is designed to deliver dependable ignition performance, smooth engine starts, and improved fuel efficiency. Its platinum center electrode firing tip helps prevent gap erosion, allowing the spark plug to maintain consistent spark delivery and longer service life compared to conventional spark plugs.
The copper core center electrode improves heat transfer to help maintain optimal engine temperatures and reduce fouling. A high alumina ceramic insulator provides excellent electrical insulation and thermal conductivity, supporting stable combustion and reliable ignition performance. The multi-rib insulator helps prevent flash-over, while the nickel-plated shell protects against corrosion and enhances durability for extended use.
Autolite platinum spark plugs are engineered to meet the performance needs of many gasoline engines, providing reliable ignition and consistent engine operation.
