Engineered for demanding conditions, this spark plug delivers reliable starts, improved fuel efficiency, and enhanced throttle response. Upgrade your motorcycle's ignition system with Denso's advanced technology.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Denso IW31 Iridium Spark Plug utilizes a fine wire iridium center electrode, measuring a mere 0.4mm, which significantly reduces voltage requirements and enhances firing performance. The 360° laser-welded electrode ensures an exceptional seal, providing unmatched durability even under the most extreme operating conditions. The tapered cut and U-groove design of the ground electrode create a large volume area, optimizing flame kernel development for a more complete and efficient combustion. This iridium spark plug is a resistor type and features a threaded stud terminal configuration. The IW31 spark plug offers superior resistance to wear and provides consistent performance over its lifespan, ensuring your engine runs smoothly and efficiently.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eIridium electrode is six times harder than platinum and withstands temperatures up to 4,000°F, ensuring long-lasting performance.\u003c\/li\u003e\n    \u003cli\u003eThe ultra-fine 0.4mm iridium electrode reduces voltage requirements and improves firing performance for quicker starts.\u003c\/li\u003e\n    \u003cli\u003e360° laser welding provides a superior seal, offering exceptional resistance to wear and corrosion.\u003c\/li\u003e\n    \u003cli\u003eTapered cut and U-groove ground electrode enhances flame kernel development for improved combustion.\u003c\/li\u003e\n    \u003cli\u003eResistor type plug reduces radio frequency interference (RFI) for smoother electronic operation.\u003c\/li\u003e\n    \u003cli\u003eDesigned for easy installation with a 13\/16\" hex size.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eBrand: DENSO\u003c\/li\u003e\n    \u003cli\u003eProduct Name: Spark Plug\u003c\/li\u003e\n    \u003cli\u003eVendor Part Number: IW31\u003c\/li\u003e\n    \u003cli\u003eCenter Electrode Type: Fine Wire\u003c\/li\u003e\n    \u003cli\u003eElectrode Tip Material: Iridium\u003c\/li\u003e\n    \u003cli\u003eElectrical Resistance: 5k Ohms\u003c\/li\u003e\n    \u003cli\u003eHeat Range: 10\u003c\/li\u003e\n    \u003cli\u003eSpark Gap: 0.76 mm\u003c\/li\u003e\n    \u003cli\u003eThread Size: 14 mm\u003c\/li\u003e\n    \u003cli\u003eThread Reach: 19.1 mm (3\/4\")\u003c\/li\u003e\n    \u003cli\u003eHex Size: 20.6 mm (13\/16\")\u003c\/li\u003e\n    \u003cli\u003eTerminal Configuration: Threaded Stud\u003c\/li\u003e\n    \u003cli\u003eCenter Electrode Projection: Non-Projected\u003c\/li\u003e\n    \u003cli\u003eGround Electrode Shape: Taper Cut, Grooved\u003c\/li\u003e\n    \u003cli\u003eType: Resistor\u003c\/li\u003e\n    \u003cli\u003eUnits: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003ePlease verify compatibility with your motorcycle's engine before installation.
