Features<\/h5>\n
    \n
  • 0.6mm Iridium Alloy Center Electrode<\/strong>
    \nIridium Alloy Center Electrode reduces voltage requirement as well as improving ignition performance and durability.<\/li>\n
  • Outer Electrode with Platinum Chip<\/strong>
    \nThe Outer Electrode incorporates a square platinum chip which improves urability, and when combined with the iridium center electrode boosts ignition performance.
    \nThe Outer Electrode features a shortened tip design and tapered shape while
    \nmaintaining the necessary space for proper ignition.<\/li>\n
  • Short Type Outer Electrode (Anti-Vibration)<\/strong>
    \nThe outer electrode has been shortened and engineered with the ideal shape to decrease weight for resistance against vibration. This anti-vibration design improves longevity of the outer electrode.<\/li>\n
  • Thermal Edge<\/strong>
    \nAfter long idling or various combustion conditions carbon buildup can occur causing misfires. The Thermal Edge of the ceramic insulator will discharge to help decrease carbon deposits.<\/li>\n
  • Spark Support Gap<\/strong>
    \nDischarges will occur in the Spark Support Gap (space between the tip of insulator and the base of the outer electrode) to help prevent carbon buildup.<\/li>\n<\/ul>\n<\/div>\n
    \n
    Performance and Efficiency<\/h5>\n
      \n
    • Increased Ignition Performance<\/strong>
      \nDecreased voltage requirement strengthens ignition performance under harsh conditions like lean mixture or high boost pressure.<\/li>\n
    • Improved Durability<\/strong>
      \nNew material and design improves durability, which allows for use under hard combustion conditions like continuous high load during circuit driving or aggressive tuning.
      \n* Improper combustion condition and wrong heat range selection might cause damage to sparkspark plug.<\/li>\n
    • Decreased Carbon Deposits<\/strong>
      \nThermal Edge and Spark Support Gap help prevent carbon buildup for better ignition under various combustion conditions.<\/li>\n<\/ul>\n
      \n
      Special Design RE-type for Rotary Engines<\/h5>\n

      Rotary engines reciprocating design have a different mechanism and combustion condition. RE-type spark plugs are specially designed to meet the different requirement for rotary engines. The straight shape platinum outer electrode enables reliable ignition performance.<\/p>\n<\/div>\n
