NGK 2851 V-Power GR5 Spark Plug 14mm Thread Heat Range 5 Resistor

The NGK 2851 V-Power GR5 spark plug is a nickel alloy replacement spark plug built to OE specifications. It gives reliable performance and better ignitability than a standard nickel plug. It is a good choice for engines that came with nickel alloy plugs from the factory.

Key Features:

• V-cut nickel alloy center electrode and concave ground electrode improve ignitability, for quicker starts and a smoother idle
• High-grade alumina silicate ceramic insulator gives strong dielectric performance and good heat transfer
• Copper core helps remove heat and improves conductivity
• Trivalent metal plating resists corrosion and seizing, which makes installation and removal easier
• Corrugated insulator ribs help prevent flashover
• Triple seals help prevent leakage
• Built-in resistor (5K ohm) helps suppress radio interference
