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.
This plug conforms to the Japanese Industrial Standards height of 53mm from the seat to the top of the terminal nut.
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.
