NGK's Standard Plugs are constructed for longer life and optimum performance. This plug has a screw-on terminal nut over a threaded terminal stud to allow it to be used with either connector type.
It also features a tapered seat design that uses the outer shell to create a seal between the plug and combustion chamber.
This spark plug features trivalent metal plating for superior anti-corrosion and anti-seizing properties, as well as corrugated ribs to prevent flashover.
It also includes a pure alumina silicate ceramic insulator to provide superior strength and better heat transfer. Additionally, a copper core aids in heat removal and a triple seal prevents leakage.
