NGK 6777 spark plug for the 2013-2024 Honda CBR600RR 599cc and other vehicles fires the spark that ignites the fuel mixture in the cylinder. It is one of the NGK spark plugs recommended for vehicles that use OE fine wire iridium alloy plugs.
Hard starting, a misfire or rough running can mean the plugs are worn. A weak ignition coil or a clogged air filter can also be behind those signs, so find the cause before buying plugs. If a worn plug is the cause, this one replaces it.
The listing covers a wide range of Honda models, including the 2015-2024 Honda CBR600RR ABS 599cc and the 2001-2004 Honda CBR600F F4I 599cc, alongside the 2013-2024 Honda CBR600RR 599cc. Riders with another model should open the "Vehicles it fits" section and check their exact model and engine.
