Description
Iridium spark plugs deliver a hotter, more efficient spark with significantly extended service intervals—meaning fewer plug changes and more reliable ignition performance over the life of your engine. The smaller iridium electrode requires less firing voltage while maintaining superior combustion consistency, a critical advantage for high-performance and forced-induction applications where standard plugs fall short. If you’re running a demanding engine setup, upgrading to iridium technology is a straightforward way to improve reliability and reduce maintenance downtime.
