Product Details

The NGK WR5IX Iridium IX spark plug delivers superior performance and extended service life through its advanced iridium alloy center electrode. Designed for a wide range of automotive, motorcycle, and small engine applications, this spark plug combines NGK's proven OE-quality engineering with the durability benefits of iridium technology.

Key Features:

  • Iridium center electrode for maximum durability and longer life compared to traditional copper plugs
  • 0.6mm laser-welded fine wire center electrode for improved ignitability and throttle response
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
  • Corrugated ribs prevent flashover and ensure consistent performance
  • Triple gasket seal eliminates combustion gas leakage
  • Pure alumina silicate ceramic insulator for superior strength and heat transfer
  • Copper core aids in heat dissipation for optimal thermal performance

NGK Iridium IX spark plugs offer improved fuel efficiency, smoother acceleration, and reduced emissions. The fine wire iridium center electrode requires lower voltage to fire, ensuring reliable starts and consistent performance across a wide temperature range. Backed by NGK's 80+ years of ignition expertise and OE manufacturing standards, the WR5IX delivers reliable operation you can trust.
