Description

The NGK 5258 is a Laser Iridium spark plug designed for performance enthusiasts. It features a fine wire center electrode made of Iridium, offering high durability and a consistently stable spark due to its extremely high melting point. This spark plug also includes trivalent metal plating for superior anti-corrosion and anti-seizing properties, corrugated ribs to prevent flashover, and a pure alumina silicate ceramic insulator for strength and heat transfer.
