    Don’t settle for second-rate performance that constantly lets you down – replace your failing or worn-down spark plugs with MSD Iridium Spark Plugs instead and rev up your engine for optimal performance.

    These top-of-the-line spark plugs come uniquely engineered for efficient combustion to generate the most power possible and sport a proprietary design with center tips made from iridium to promote the best spark and the improved resilience you need for a long service life. Featuring copper center cores and a special ceramic material, each plug is also capable reducing the voltage requirement for a spark and providing enhanced dielectric strength in the plug housing. MSD iridium plugs come with machine-ground straps enhanced with Yttrium to withstand the extreme heat of your high horsepower ignition.

    Your MSD Iridium Spark Plugs are sold individually or in packs of four and are backed by a limited warranty.
