NGK Nickel V-Grooved Spark Plug

The NGK Nickel Spark plug range is the time-proven and trusted go-to replacement option for many professional and hobby mechanics to maintain the high performance and reliability of their vehicles.

• Cold-rolled threads prevent cross-threading and damage to cylinder heads
• Trivalent plating eliminates the need for anti-seize compounds
• High-grade alumina silicate ceramic quickly dissipates heat

Each and every spark plug manufactured by NGK is designed to meet the most rigorous standards, ensuring the ability to deliver reliability and consistent performance under all conditions. Each plug plays a major role in helping improve performance, fuel economy and the overall optimum efficiency of your engine, helping to make a significant contribution in the reduction of emissions.

NGK uses 98% pure Copper in place of the iron core found in conventional plugs and is the secret to their wide heat range. The Copper core electrode provides superior heat conductivity and combined with the alumina silicate insulator allows for quicker dissipation of heat for more reliable starting and aids in the cooling of the electrode tip and insulator tip; thus, preventing hot spots that could cause pre-ignition. Copper cored electrodes also mean that longer insulator noses can be used to protect against fouling and increase spark reliability.

Trivalent plating is the silver finish on NGK plugs that is specifically developed to prevent corrosion of the bare metal threads and metal surfaces of the spark plug, whilst allowing dry fitment without the need for anti-seize compounds during services.

All NGK spark plugs use copper cores but rely on precious metals for their electrode construction as copper alone is superior for heat dissipation but is a soft metal with a low melting point.

NGK Standard spark plugs have special nickel alloy electrodes, specifically shaped/ground for each application, that optimises spark performance and increases the durability of the spark plug, for longer service life.

NGK Nickel V-Grooved Spark Plugs feature a specially designed v-groove nickel alloy centre electrode profile that forces the spark to be created at the very tip/edge of the electrode, improving ignitability and spark strength, whilst reducing the voltage required to create the spark. Ideal for upgrading your standard OE spark plugs
