    NGK 90992 NGK laser iridium spark plug for the 2020-2022 Honda CRF1100L Africa Twin 1084cc and other vehicles ignites the fuel mixture in the cylinder. This laser iridium high ignitability spark plug is engineered for OE applications. Its ground electrode has a raised platinum pad or platinum fine wire tip for even wear in distributorless ignition systems.

    • Laser Iridium High Ignitability design with an SPE tip and an iridium alloy center electrode
    • Iridium is six times as dense as platinum and has an extremely high melting point, suited to modern high efficiency engines
    • Square platinum ground electrode shape for ignitability and service life in high heat engines
    • Solid copper core, 98% pure, for heat dissipation, conductivity and wide heat ranges
    • Trivalent metal plating resists corrosion and seizing, which eases installation and removal

    Quick facts

    • Part: NGK 90992 NGK laser iridium spark plug
    • Also called: laser iridium high ignitability spark plug
    • Fits: 2020-2022 Honda CRF1100L Africa Twin 1084cc and other vehicles
    • Condition: New

    A weak ignition coil, a vacuum leak or a clogged injector can cause hard starting, a rough idle or a misfire just as worn plugs can, so find the cause before buying a plug. This plug is recommended for vehicles that have OE SPE iridium alloy plugs.

    Yes. NGK 90992 is listed for the 2020-2022 Honda CRF1100L Africa Twin 1084cc, which takes four plugs. For another model, look up your own bike and year in the "Vehicles it fits" section.

    What is the center electrode on the NGK 90992 made of?

    The NGK 90992 has an iridium alloy center electrode and a square platinum ground electrode. Iridium is six times as dense as platinum and has an extremely high melting point.

    Do NGK iridium spark plugs like this one have a solid copper core?

    Yes. This plug has a solid copper core that is 98% pure, which helps with heat dissipation and conductivity. The insulator is high grade pure alumina ceramic.

    Does the plating on the NGK 90992 make removal easier?

    Yes. The NGK 90992 has trivalent metal plating that resists corrosion and seizing, which eases installation and removal.

    What is on the ground electrode of this laser iridium spark plug from NGK?

    A raised platinum pad or platinum fine wire tip, which gives even wear in distributorless ignition systems and improved spark performance.
