  • Four yttrium-enhanced nickel ground electrodes provide optimum access to the air/fuel mixture while reducing gap wear and oxidation for extended service life
  • Factory pre-set electrode gap — no gapping or adjustment required for easy installation
  • Projected-tip design reaches self-cleaning temperatures faster for quicker cold starts
  • Resistor-equipped to suppress ignition interference
