IMR9B-9H NGK Iridium Spark Plug

NGK Iridium Motorbike Spark Plugs use a strong metal iridium which offers improvements in starting, idling & throttle response.

• Iridium has an extremely high melting point & offers greater protection from chemical attack.
• Allows 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 & lower voltage requirements.
