Product Details

The DENSO 5373 Iridium Power spark plug delivers superior ignition performance through advanced materials engineering. Featuring the world's smallest 0.4mm iridium center electrode, this plug provides a more concentrated spark for improved combustion efficiency.

Key Features:

  • Ultra-fine 0.4mm iridium center electrode for optimal spark concentration
  • Enhanced throttle response and acceleration
  • Improved fuel efficiency through more complete combustion
  • Superior durability and extended service life
  • Iridium construction resists wear and erosion
  • Reduced voltage requirements for reliable cold starts

DENSO Iridium Power spark plugs represent a significant upgrade over conventional copper or platinum plugs, offering measurable improvements in engine performance, fuel economy, and plug longevity. The ultra-fine iridium tip requires less voltage to fire while creating a more powerful spark in the combustion chamber.
