Employing a revolutionary 360 degrees laser welding process, Denso has created a spark plug unlike anything on the market today.

Features:

  • Platinum center electrode utilizes platinum to shrink the surface area of the center electrode tip for maximum firing performance and minimum voltage requirements
  • Platinum ground electrode resists gas and electrical erosion and corrosion extending service intervals to 60,000 miles,000 miles
