Description

The NGK B-4L is a nickel spark plug designed for improved ignitability. It features a unique V-cut in the center electrode, which directs the spark to the edge for more rapid development and reduced quenching. Trivalent metal plating provides superior anti-corrosion and anti-seizing properties, while corrugated ribs prevent flashover. The pure alumina silicate ceramic insulator offers superior strength and heat transfer, and the copper core aids in heat removal. Triple seals prevent leakage.
