- Autolite HT1 High Thread Spark Plug
- Autolite® High Thread Pro® plugs are an OE patented design exclusively for Ford 3V engines. Its comprehensive seal provides more durability, greater power, improved heat transfer, and a more focused ignition, ensuring your engine reaches and maintains optimal performance levels.
- Engineered with a fine-wire platinum design that provides more focused ignition power and longer service life.
- The ground strap provides improved heat transfer over standard J-gap plugs.
- Its proprietary design improves performance for heat management, fouling resistance & increased dielectric strength.
- The position of the thread above the cylinder head seating allows for a more compressive seal.
- Designed with a nickel-plated shell that delivers increased protection against corrosion.
