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.

The close up section shows the
annular gap between the centre
electrode and insulator nose which
provides cold fouling protection.
Should current try to leak away
across a carbonised insulator a
spark can occur between the
electrode and the insulator thus
burning away the carbon deposit.
