Description
The spark plug has a tapered cut U-Groove ground electrode to increase ignitability and decrease quenching. Its machine-rolled threads prevent seizing or cross-threading during installation and removal. The insulator is made of purified alumina powder for strength and thermal conductivity, with five ribs to prevent flashover.
