2 X NGK Copper Core Motorcycle / Bike Spark Plugs - CR9EH-9

    The NGK Standard Spark plug range is are engineered specifically for OE applications and provide OE quality nickel alloy reliable performance and design.

    • Cold-rolled threads prevent cross-threading and damage to cylinder heads
    • Trivalent metal plating delivers superior anti-corrosion and anti-seizing properties ensuring ease of installation and removal
    • 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.

    Standard Copper Core Plugs - NGK uses Copper wire 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, allowing quicker dissipation of heat and helping 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!
