Two championship event wins in one weekend for TOYOTA GAZOO Racing
Iridium Performer Spark Plugs are the ultimate option for customers seeking the maximum plug performance and durability particularly in high-pressure lean-burn engines – offering outstanding sparking ability and voltage decrease.
- Improved performance & durability: Easier fi ring: The cross groove on the surface of the Iridium alloy centre electrode effectively creates four ‘mini-tips’ that fi re more readily than one large tip. Better spark: The cross groove design strengthens the fi eld intensity of the electrode, improving sparking performance. Lower required voltage: cross groove also suppresses voltage dispersion, resulting in a 4kV lower required voltage advantage over competitor plugs and as a result, better performance and durability.
- Proving longer life: Required voltage is by: 1) Unique “Iridium alloy”. 2) Cross groove electrode, resulting in a longer life than conventional plug.
- Cross groove design (M18mm plug): Four small electrodes created by cross groove improve sparking performance and suppress dispersion in voltage value, for an outstanding voltage decrease (patent USA6215234).
Iridium alloy pad with cross groove: The cross groove cut into the Iridium centre electrode tip enhances spark performance and lowers the discharge voltage.
The reduced discharge voltage results in increased operating hours over a SAVER plug.
