NGK NGK Laser Iridium Spark Plug P/N:5766
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.
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.
It is listed for a wide range of Honda models, including the 2020-2022 Honda CRF1100L Africa Twin DCT 1084cc and the 2020-2022 Honda CRF1100L4 Africa Twin Adventure Sports ES 1084cc. This listing is one plug, and the quantity depends on the model; each of the Africa Twin models named above takes four.

Is the NGK 90992 right for the 2020-2022 Honda CRF1100L Africa Twin 1084cc?
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.
