NGK's 3112 B-4L Nickel Spark Plug, part of the V-Power series, boasts a distinctive V-cut in the center electrode that directs the spark to the electrode's edge, promoting rapid spark development and reducing quenching. This design increases ignitability, enhancing overall engine performance. Trivalent metal plating provides superior anti-corrosion and anti-seizing properties, while corrugated ribs prevent flashover. The pure alumina silicate ceramic insulator offers exceptional strength and efficient heat transfer. Additionally, the copper core aids in heat dissipation, and triple seals prevent leakage, ensuring reliable and long-lasting performance. Trust NGK for high-quality spark plugs that deliver optimal engine efficiency.
