  • Maintaining the necessary space for proper ignition
  • Short Type Outer Electrode (Anti-Vibration)
  • The 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
  • Thermal Edge
  • After 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
  • Spark Support Gap
  • Discharges 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

Special Design RE-type for Rotary Engines. 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.
