These plugs also feature copper center cores, special ceramic material to enhance the dielectric strength of the plug housing, and machine-ground straps enhanced with Yttrium to handle the heat of your high horsepower ignition. On the street, at the track, or up and over the trails, MSD iridium spark plugs will outperform and outlive the competition.
