The center tip of the plug is made from iridium to promote the best spark and increase resilience. A proprietary ceramic material enhances the dielectric strength of the plug housing forcing the spark, even under extreme cylinder pressures, to jump across the plug gap to the ground electrode. This electrode is machined to expose more spark to the incoming gases to promote the most effective combustion event possible.

These were for a friend's 2002 Jeep Classic. Arrived in perfect shape. No issues. Gapped just as they needed to be, installed and working great. Being iridium tipped, probably the last time I'll have to put plugs in this car. Clearly MSD has someone else make the plug and just rebrand it with their name, but from all outside appearances to be a very quality plug. Wished I could have gotten 6, but could only find pkgs of 4.
