The Iridium composition of these spark plugs provides a high melting point and great strength, offering excellent wear resistance and durability. Iridium allows for small, efficient electrode designs, ensuring reliable cold starting and quick acceleration. The Iridium fine-wire electrode helps burn away carbon deposits on the tip of the plug as they form, while the one-piece suppressor seal blocks radio frequencies that can affect vehicle electronics. The suppressor seal also meters spark energy for long electrode life and helps prevent combustion leakage.
