- Iridium offers better engine idle stability and smoother performance
- Iridium allows for smaller, more efficient electrode designs for improved cold starting and quicker acceleration
- Iridium fine-wire electrode helps improve ignition of the fuel and burns away carbon deposits on the tip of the plug as they form, to helping improve fuel economy
- One piece suppressor seal blocks radio frequencies that can affect vehicle electronics
- Suppressor seal meters spark energy for longer electrode life and seals against combustion leakage
