13 best msd iridium spark plugs

MSD Iridium spark plugs are designed to enhance the performance of your vehicle's ignition system. Iridium is known for its durability and high melting point, making it an excellent material for spark plug electrodes.These plugs offer improved spark efficiency and longevity compared to traditional copper or platinum plugs.

The fine-wire iridium center electrode ensures a consistent and stable spark, promoting efficient combustion and better fuel efficiency. This can lead to improved throttle response and overall engine performance. Additionally, the iridium construction helps prevent electrode wear over time, ensuring a longer lifespan for the spark plug.

MSD, as a brand, is recognized for its high-performance automotive products, and their Iridium spark plugs are no exception. These plugs are often chosen by enthusiasts and those looking to maximize the ignition system's capabilities in high-performance or modified vehicles.

Remember to consult your vehicle's manual and consider your driving needs before upgrading to performance spark plugs. While they can offer benefits in certain scenarios, it's essential to ensure compatibility with your engine and driving conditions.

MSD Ignition

Based on 9 reviews Check latest price

Product description

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.

  • MSD's proprietary ceramic formula provides the highest dielectric strength
  • Yttrium ground electrode reduces the chance of pre-ignition
  • Iridium tip improves cold starts
