The small part screwed into the cylinder head that makes the spark to ignite the air-fuel mixture and keep the engine running.
NGK offers this spark plug for HONDA CRF 250, CRF 250 X 2004-2019. On every turn (two-stroke) or every other turn (four-stroke), the ignition sends a high voltage to the plug: a spark jumps between its electrodes and ignites the mixture in the cylinder.
The benefits:
NGK, the Japanese manufacturer founded in 1936 with roots in the ceramics industry, is the leading original-equipment spark plug supplier; its plug caps contain a ceramic resistor that suppresses interference without affecting how the engine runs.
Rounded or eroded electrodes, black or oily deposits, a cracked insulator, hard starting or misfires under acceleration: replace the plug.
Cross-Mania tip: Screw it in by hand first on a clean thread, tighten it to the torque or angle given by the manufacturer and push the plug cap fully home until it clicks.
