NGK Platinum Spark Plug
NGK Platinum Spark Plugs are high-performance spark plugs specifically developed for improved spark performance and greater service intervals over factory nickel plugs.
- Fine platinum tip for consistent spark performance
- 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 Laser Platinum spark plug (standard Platinum) are developed alongside OE manufacturers to ensure quality and durability standards. They usually feature a single laser-welded Platinum centre electrode with between 1 and 4 ground electrodes, dependent on the spark plugs design and application. The latest innovations include fine wire platinum centre electrodes and high-grade alumina silicate ceramic insulators making them ideal OE replacements or performance upgrade plugs.
NGK premium Platinum spark plugs feature a single Platinum fine wire centre electrode that gives a hard, durable electrode that increases service life over factory plugs. The addition of a trapezoidal ground electrode profile also gives a wider flame ignition to improve fuel burn and ensures a more focused spark with better ignitability, making them ideal for the wide range of temperatures experienced in modern performance engines.
