Spark Plug 9IR5Y Single Pack

MSD’s spark plugs are engineered to improve the efficiency of the combustion process to create the most power possible combined with increased durability. 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.

  • Proprietary plug design inside and out
  • Designed for use on high performance vehicles that utilize high output ignition systems
  • Machined electrode increases exposure to the flame to improve combustion
  • MSD’s proprietary ceramic formula provides the highest dielectric strength
  • Yttrium ground electrode reduces the chance of pre-ignition
  • Iridium tip improves cold starts
  • Designed to outlast other performance plugs on the track or on the street
  • All spark plugs tested prior to packaging and shipping
  • Shorty-style plugs for applications where space is limited

Spark Plugs from the Ignition Exports
What makes MSD’s Iridium plugs a cut above the competition? Besides our race winning experience of firing 330 mph top fuel cars, the endurance of 500 mile stock car racing and the brutal expectations of off-road racing, our new spark plugs are designed to perform from the inside out.

  • The center machine ground strap enhanced with Yttrium can withstand the heat associated with high horsepower ignitions unlike any other spark plug
  • Believe it or not, spark plugs need to be cooled or they can cause detonation. MSD’s spark plug has a copper core that transmits heat to the cylinder head to help prevent knock
  • This is the business end of the spark plug. Inexpensive materials cause wear over the course of millions of ignition firings. MSD’s Iridium is a must when using a high power ignition in order to keep the spark in its place
  • Spark isolation is important with high output ignitions and MSD developed a proprietary ceramic blend for the strongest dielectric strength
  • By engineering a proprietary copper center core in our plugs we have reduced the heat within the plugs to allow the increase of life on the insulator tip which means you need to change out your plugs less often
