Description
The Autolite Copper Spark Plug has traditional nickel electrodes and its copper core improves resistance to fouling. The power tip extends further into the combustion chamber to aid in self-cleaning, reducing fouling at low RPM's, and pre-ignition at high speeds. It has a 1/2" reach surface gap plug specifically designed for high lift Flathead engine applications.
Features
- Guaranteed to deliver quick starts, good fuel economy and smooth acceleration.
- Copper core center electrode for higher thermal conductivity.
- Specially engineered high nickel alloy center and ground electrode for extended life.
- High alumina ceramic for high dielectric strength.
- Leak proof, heat fused internal seal for durability.
- Multi-rib insulator prevents flash-over.
