Iridium IX
Iridium Plugs are high-performance plugs with measures against plug fouling: they feature a faster spread of combustion than original plugs, and they are also provided with a “thermo edge” at the top of the insulator.
Iridium MAX
Iridium MAX plugs have the same performance as Iridium IX plugs but also achieve a long life. They maintain their performance longer than platinum plugs.
IRI series
The IRI Series plugs are designed for tuned engines that require a high heat rating; they are Iridium Plugs with excellent ignition and acceleration characteristics.
