Product Details

The DENSO 5378 Iridium Power spark plug delivers enhanced ignition performance through advanced electrode technology. Engineered with the world's smallest 0.4mm iridium center electrode, this plug provides superior ignitability and throttle response compared to conventional spark plugs.

Key Features:

  • Ultra-fine 0.4mm iridium center electrode for improved firing efficiency
  • Iridium construction offers six times greater hardness than platinum
  • Enhanced fuel efficiency and acceleration response
  • Superior anti-fouling properties for reliable performance
  • Longer service life compared to standard copper plugs
  • Designed for demanding driving conditions

DENSO Iridium Power spark plugs are manufactured to OE specifications, ensuring precise fitment and reliable ignition performance. The ultra-small center electrode requires lower voltage to fire while concentrating spark energy for more complete combustion.
