NGK 1233 BPR5EY V-Power Spark Plug Nickel Copper Core 14mm

The NGK 1233 V-Power spark plug (BPR5EY) is a nickel alloy replacement plug built to OE standards. Its V-cut center electrode and concave ground electrode improve ignitability over standard nickel plugs. This helps with quicker starts and smoother idle. It works well as a direct OE-style replacement or a step up from a standard plug.

Key Features:

• V-grooved nickel alloy center electrode places the spark closer to the air/fuel mixture for easier ignition
• Concave ground electrode improves ignitability and lowers ignition system voltage requirements
• Solid copper core (98% pure copper) improves heat dissipation, conductivity and heat range
• High-grade alumina silicate ceramic insulator for strong dielectric performance
• Cold-rolled threads help prevent cross-threading and cylinder head damage
• Trivalent metal plating resists corrosion and seizing for easier installation and removal
• Built-in resistor helps suppress radio frequency interference
