NGK 1266 BCPR5EY V-Power Spark Plug 14mm Nickel Copper Core

The NGK 1266 V-Power spark plug (BCPR5EY) is an OE-style nickel alloy spark plug. It improves ignitability over standard nickel plugs. Its V-cut center electrode directs the spark to the electrode edge. That helps the flame kernel develop quickly, for quicker starts and smoother idle. It suits engines originally equipped with nickel alloy plugs.

Key Features:

• V-cut nickel alloy center electrode: increases ignitability and reduces spark quenching
• Solid copper core: improves heat dissipation, conductivity and heat range
• High-grade alumina silicate ceramic insulator: provides strength and dielectric performance
• Trivalent metal plating: resists corrosion and seizing for easier installation and removal
• Cold-rolled threads: help prevent cross-threading and cylinder head damage
• Corrugated insulator ribs: help prevent flashover
• Triple seals: help prevent combustion leakage
