DENSO Iridium Spark Plugs IKH20, box of 4


By using a 0.4 Millimeter diameter iridium alloy center electrode and a special ground electrode, IRIDIUM POWER realizes spark performance unseen until now. It steadily gives a high level of response under a variety of driving conditions. The result? Increased acceleration and torque compared to regular plugs.


  • Built-In, Highly Reliable Resistor: Features A Highly Reliable, 5,000 Ohm Monolithic Resistor Specification To Reduce Electromagnetic Noise That May Affect Electronic Devices
  • Highly Corrosion Resistant, Burnished Nickel Plating: Highly Resistant To Corrosion And Rust Even While Touring In Continually Rainy Weather And During Motocross Events
  • 360 Degree Laser Welding: The Process Used To Mount The Iridium Tip Is A Highly Reliable “All-Around Laser Welding” Process That Is Able To Withstand All Kinds Of Driving Conditions
  • Projected Center Electrode: To Improve Ignitability, The Center Electrode Protrudes More Than With Conventional Type Plugs Improving Both Acceleration Response Time And Performance
  • 0.4 Millimeter Diameter Ultra ?ne Iridium Center Electrode: Enables The Reduction Of Voltage Necessary To Cause The Spark, And Greatly Improves Ignitability
  • Taper Cut Ground Electrode: The Tip Of The Ground Electrode Is Cut To A Fine Taper To Reduce The Adverse Effects Of Quenching, Which Greatly Improves Fuel Ignitability
  • The U-Shaped Groove On The Ground Electrode Insures That The Inside Surface Area Is Large Enough To Generate The Flame Kernel
  • Insulator Projection: The Projection Of The Insulator Is Optimally Designed Based On Each Plug's Thermal Value
  • A Terminal Nut Is Attached That Fits With Most Of The World’s Spark Plug Cables (Can Be Removed For Installations That Do Not Require One)
