Product Details

The DENSO 5309 Iridium Power spark plug delivers enhanced ignition performance through advanced materials engineering. Designed for demanding automotive applications, this plug utilizes premium iridium technology to provide superior combustion efficiency and long-lasting durability.

Key Features:

  • Ultra-fine 0.4mm iridium center electrode—the world's smallest diameter for concentrated spark energy
  • Iridium alloy construction provides exceptional durability and wear resistance
  • Improved ignitability for better throttle response and fuel efficiency
  • Enhanced performance across a wide range of operating conditions
  • Extended service life compared to conventional copper or platinum plugs
  • Precision manufacturing ensures consistent quality and fitment

DENSO's Iridium Power technology focuses spark energy through an ultra-fine center electrode, creating a more efficient combustion process. This results in smoother engine operation, improved acceleration, and optimized fuel consumption. The iridium construction withstands extreme temperatures and electrical erosion, maintaining peak performance over extended intervals.
