Iridium IX - the alternative for even more power

These high-performance spark plugs with precious metal iridium middle electrode are used by manufacturers as original equipment. They were specially developed for the newest engine technologies, but they are also an alternative to the standard type for older models in order to completely utilise power reserves.

Special characteristics:

• The electrode material iridium is almost completely resistant to spark erosion.
• Iridium enables an especially narrow middle electrode, with a diameter of only 0.6 mm.
• With the small middle electrode, more ignitable mixture reaches the ignition sparks. That leads to a reliable ignition and better spreading of the flame front.
