Product description

  • IK20TT Twin Tip Plug Tightneing Torque (Nm) 22 1 - Earthed Electrode Diameter (mm) 14 Thread Length (mm) 19
  • The Finest Twin Tip plug with improved acceletation, fuel economy and longevity compared to single tip plugs. The quenching effect has been decreased by forming the electrode into a double needle shape. As a result, the flame kernel rapidly develops and the engine s power is drawn out to its maximum potential. DENSO IRIDIUM TT spark plugs have a 0.4 mm iridium alloy center electrode and a 0.7 mm needle-type platinum alloy ground electrode.
  • The iridium tip is mounted with an All-around Laser Welding method that insures high reliability even under the most severe driving conditions.
  • 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.
  • All specification types include an embedded, highly reliable, monolithic resistor to eliminate electoromagnetic noise interference from all kinds of electronic devices.
