NGK 7556 spark plug for the 2008-2016 Honda CBR1000RR 999cc, the 2017-2019 CBR1000RR 998cc and other vehicles ignites the air-fuel mixture in the cylinder. Among NGK spark plugs, it pairs an iridium center electrode with a platinum ground electrode.
Hard starting, a rough idle or misfires can mean a spark plug is worn, but other ignition or fuel faults cause the same signs. Find the cause first: with the engine off and cool, look at each removed plug for worn electrodes, deposits or a cracked ceramic.
This iridium spark plug fits the 2008-2016 Honda CBR1000RR 999cc, the 2017-2019 Honda CBR1000RR 998cc, the 2021-2024 Honda CBR1000RR ABS 998cc and the 2021-2024 Honda CB1000R Black Edition 998cc.
