  • Tapered center wire electrode with a platinum pad that reduces the firing diameter and helps improve the firing efficiency by concentrating and directing energy needed to fire the plug with less voltage.
  • One-piece integral suppressor seal that helps reduce radio frequency interference, meters spark plug energy to help provide long electrode life, and seals against compression leakage.
  • Reduced sparking voltage & greater corrosion protection when compared to conventional spark plugs.
