Iridium IX: Designed for the Performance Enthusiasts

The NGK Iridium IX spark plug is designed for performance enthusiasts, claiming to deliver enhanced throttle response and superior resistance to fouling thanks to its long insulator nose. The anti-corrosion trivalent metal plating on the body and threads of these iridium plugs reduces the likelihood of them getting stuck in a vehicle’s cylinder head, even after many years of hard service out on the water.

These NGK Iridium spark plugs are tested to the highest original equipment standards, providing the performance and service upgrade a vehicle deserves.

All NGK spark plugs also must pass extensive testing procedures and quality checks to ensure fit and performance.

  • Combustion pressure testing to maintain stable performance
  • Acceleration testing for improved acceleration performance
  • Mechanical vibration testing
  • Thermal shock testing to -40oF
  • Tightest resistor manufacturing process in the industry
  • Manufacturing in our ISO 11565 certified manufacturing facility
  • Gap measurement with laser precision throughout production process
  • Center electrodes are accurately positioned with 360o welding process

It’s The Spark That Starts It All

NGK Spark Pulgs

If you’ve been around marine engines, you have probably seen and heard of NGK spark plugs.  Spark plugs are an integral component of your gasoline engine ignition system, providing the final transmission of electrical current into the combustion chamber to ignite the fuel. 

Every time you get in and start your watercraft, you are most likely not thinking about what is happening inside your engine, which is how it should be.  Let’s face it, no one wants to be enjoying time on the water and experience engine issues.  The correct spark plugs are a small, yet crucial part of keeping your engine reliable and running smoothly.

NGK has built a reputation for quality and reliability with their commitment to excellence. Insure confidence in your ignition system by taking the easy step of making NGK spark plugs a part of your maintenance program.  Lewis Marine Supply stocks the majority of numbers in the NGK catalog of marine spark plugs.
