IRIDIUM IX SPARK PLUGS
Ultra fine Iridium center electrode
Tapered ground electrode to increase flame kernel expansion - Minimizes "quenching effect" through advanced design of the ground and center electrode
Superior heat range design - Every Iridium IX is designed with the ideal heat range for high performance operating cnditions
Iridium alloy - Extremely durable to heat, corrosion, and electrical wear
0.6mm Iridium center electrode tip - Designed to just the right size. It's not too thin, ensuring high durability and spark plug life. Not too thick minimizing the voltage requirement for a consistent, stable spark.
Over 90% Iridium alloy - The perfect blend to take advantage of the extremely high melting point and superior strength of Iridium under extreme high peformance conditions.
Trivalent metal plating - Superior anti-corrosion and anti-seizing properties at high temperatures.
