NGK 4306 V-Power Spark Plug LZTR5A-13 Copper Core Nickel Tip

The NGK 4306 V-Power spark plug (NGK part number LZTR5A-13) is an OE-approved copper core spark plug with a V-grooved nickel center electrode. It gives better ignitability than a standard nickel plug. It is a dependable replacement or upgrade for quicker starts, smoother idle, and efficient combustion.

Key Features:

• V-groove center electrode: The V-cut directs the spark to the edge of the electrode. This helps the flame kernel develop faster and gives it more room to expand.
• Copper core: Improves heat dissipation and conductivity across a broad heat range.
• Trivalent metal plating: Resists corrosion and seizing in the cylinder head.
• Ceramic insulator: Pure alumina silicate ceramic gives strength and good heat transfer. Corrugated ribs help prevent flashover.
• Triple seals: Help prevent combustion leakage.
• Resistor design: 5000 ohm resistance helps suppress radio-frequency interference.
