Product Information

  • Denso Resistor U-Groove Spark Plug eliminates annoying buzzing/static in your radio/electronic gear!
  • Patented U-Groove technology creates a larger and hotter flash front for better performance
  • Virtually eliminates fouling and erratic starts caused by poor fuel mixes
  • Delivers better fuel efficiency and improved throttle response
Denso Resistor U-Groove Spark Plug is a perfect OE replacement plug that improves ignitability and increases fuel efficiency. Why is the Denso Resistor Spark Plug better? First, patented U-groove ground electrode develops a larger and hotter flash front for more complete combustion. Threads are machine-rolled for trouble-free installation and removal. Copper-glass seal bonds center electrode and insulator together for a gas-tight seal for better heat maintenance. Five-rib design prevents flashover and decreases voltage loss. And the purified alumina powder insulator provides exceptional dielectric strength and thermal conductivity that can stand up to extreme stress. All in all, simply a better spark plug!
