• Built-in, Highly Reliable Resistor
  All specification types include an embedded, highly reliable, monolithic resistor to eliminate electromagnetic noise interference from all kinds of electronic devices.
• 360° Laser Welding
  The iridium tip is mounted with an “All-around Laser Welding” method that insures high reliability even under the most severe driving conditions.
• 0.7mm Needle-Shaped Platinum Ground Electrode
  In order to maximally prevent quenching effect, the ground electrode needs to be made as small as possible. Traditional ground electrodes could not be made too small without reducing grounding strength or increasing electrode wear.
  However, we’ve managed to attach a fine 0.7mm-diameter platinum electrode using a 360° laser welding technique.
• 0.4mm Ultra-fine Iridium Center Electrode
  Using DENSO’s exclusive iridium alloy having a very high melting point, the tip of the center electrode can be shaped very thin and fine, reducing spark voltage requirements and greatly improving ignitability.
