The iridium center electrode is not only more durable but also offers a precise spark for a cleaner combustion, reducing fuel consumption and exhaust emissions.

These MODIGT spark plugs come with a tapered electrode design, which improves combustion efficiency and reduces the risk of spark plug fouling. The tapered design allows for a more even distribution of the spark, which in turn promotes a more efficient combustion process.

The MODIGT 3521 CR9EIX spark plugs are easy to install, thanks to their insulator nose design with a laser welded ground electrode. This design ensures a secure fit and a reliable connection to the motorcycle's ignition system.

By choosing the MODIGT 3521 CR9EIX 4-pack Iridium Spark Plugs, you are investing in a high-quality, reliable, and long-lasting solution for your Suzuki GSXR or Hayabusa motorcycle. Upgrade your ignition system today and experience the difference in performance, reliability, and fuel efficiency.
