Notorious Posted April 27, 2019 Share Posted April 27, 2019 Might be a gimmick, who knows. These plugs haven’t been out long enough to give any validity to the argument over Iridium plugs yet. Even then, most of us replace Iridium spark plugs on a mileage interval that is less than what they are rated to last for anyways. Link to comment Share on other sites More sharing options...
ehsnils Posted April 27, 2019 Share Posted April 27, 2019 Wear on electrodes is just one of the factors to consider on spark plugs. There's also contamination of the insulator that could result in surface conduction and loss of spark. this is of course less of a problem with lead-free fuel than it was before.
