NGK NGK Iridium IX Spark Plug P/N:5545
NGK 6216 spark plug for the 2020 Honda CRF150R 149cc and other vehicles ignites the air-fuel mixture in the cylinder. Among NGK spark plugs, this Iridium IX design is aimed at modified and high performance engines.
A worn plug can show up as hard starting, a rough idle or slow throttle response. Before you replace the plug, rule out a weak battery, a dirty air filter or a failing ignition coil, since each of those can also make an engine start hard or idle rough.
The 2020 Honda CRF150R 149cc, the 2020 Honda CRF150R Expert 149cc and the 2014-2016 Honda CBR650F 649cc take this plug, and it fits many other Honda models too. This listing is one spark plug, and the quantity a bike needs varies by model; the 2020 Honda CRF150R 149cc takes one. Open the "Vehicles it fits" section to check your exact model and engine.
