NGK Pro-V spark plugs offer reliable performance and improved ignitability over standard nickel plugs. Engineered specifically small engine applications, the special V-cut nickel alloy center electrode and concave ground electrode of NGK's Pro-V spark plug increases ignitability providing quicker starts and smoother idle. NGK's legendary high grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance and prevents spark plug overheating. Trivalent metal plating ensures superior anti-corrosion and anti-seizing properties.

Product Features:

• V-GROOVE NICKEL: Conventional nickel alloy center electrode with V-groove provides consistent performance
• RECOMMENDED USAGE: Best for engines with OE nickel alloy plugs, not recommended on engines with factory precious metal plugs
• NGK's OE CERAMIC TECHNOLOGY: High grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance
• SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
• COLD-ROLLED THREADS: Prevents cross-threading and damage to cylinder heads
• TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal
