Product Details

The DENSO 5323 Iridium Power spark plug delivers superior ignition performance through advanced iridium technology. Engineered with the world's smallest iridium center electrode at just 0.4mm diameter, this spark plug provides enhanced durability and more efficient combustion compared to traditional copper or platinum plugs.

Key Features:

  • Ultra-fine 0.4mm iridium center electrode for improved ignitability
  • Iridium alloy construction offers six times greater hardness than platinum
  • Reduced voltage requirement for more reliable starts
  • Enhanced throttle response and acceleration
  • Improved fuel efficiency through optimized combustion
  • Extended service life compared to conventional spark plugs
  • Superior resistance to erosion and wear at high temperatures

DENSO's Iridium Power technology concentrates the spark into a smaller, more intense point for more complete fuel burn. The ultra-fine electrode requires less voltage to fire, reducing stress on your ignition system while delivering consistent performance across a wide range of operating conditions.
