One plug supplied. You may need more for your bike.
The Iridium IX spark plug is similar in design to the Platinum VX type but 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 and throttle response.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 this we can offer with Iridium IX.
