Listed below are the NGK Spark plugs that NGK specify for your motorcycle.
Either Standard Copper Core or Iridium IX Spark plugs:-

NGK Standard Copper Core - CR8EH-9

  • NGK standard spark plugs with copper cored centre electrodes for wide heat range. Copper’s superior heat conductivity dissipates the heat of combustion away from the firing end, preventing hot spots that can lead to pre-ignition.
  • A wide heat range means the spark plug performs well with either a hot or cold engine. Performing well at high speeds as well as low speeds, and stop go riding i.e. city riding.
  • Copper cored electrodes also mean that longer insulator noses can be used to protect against fouling.
  • Improved cold starting

NGK Iridium IX - CR8EHIX-9

NGK Iridium IX Spark Plugs


The Iridium IX spark plug benefits from the use of the precious metal Iridium on its centre electrode. Iridium is harder than other precious metals used in spark plug manufacture, has an extremely high melting point and offers greater protection from chemical attack. These features allow the use of an extremely small diameter electrode (0.6mm) without compromising the spark plug’s service life.
Combined with the use of the taper cut ground electrode this spark plug has superior gas flow properties and lower voltage requirements, which offers further improvements in:-
  • Starting

  • Idling

  • Throttle response

  • Enhanced Ignition Efficiency

  • Better Acceleration

  • Faster Starting & Smoother Running

  • Longer Life

  • Better Fuel Consumption

Iridium spark plugs are used by some of the worlds leading race teams and as original equipment in many high performance road and off road machines. Owners who want the very best performance from their bikes will want the best spark plug and NGK offer this with Iridium IX.
