Engineered for superior ignition and longevity, this spark plug delivers enhanced fuel efficiency and smoother operation. Experience the difference that Denso's cutting-edge technology brings to your ride.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Denso IU31A Iridium Spark Plug is designed for enthusiasts and professionals seeking the ultimate in ignition performance. Featuring an iridium electrode that is six times harder than platinum and capable of withstanding temperatures up to 4,000°F, this plug ensures exceptional durability and reliability. The ultra-fine 0.4mm iridium electrode reduces voltage requirements while dramatically improving firing performance. A 360° laser-welded electrode provides a robust seal, resisting wear even under extreme conditions. The ground electrode incorporates a tapered cut and U-groove, creating a large volume area at the flame's center for enhanced combustion. This resistor-type spark plug with a 10 mm thread size and 19.1 mm (3\/4\") thread reach guarantees a precise fit and optimal function.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003eIridium electrode provides exceptional durability and longevity.\u003c\/li\u003e\n \u003cli\u003eUltra-fine 0.4mm electrode enhances firing performance and reduces voltage requirements.\u003c\/li\u003e\n \u003cli\u003e360° laser welding ensures a robust seal, even under extreme conditions.\u003c\/li\u003e\n \u003cli\u003eTapered cut and U-groove ground electrode maximizes flame volume for improved combustion.\u003c\/li\u003e\n \u003cli\u003eResistor type plug minimizes electrical noise and interference.\u003c\/li\u003e\n \u003cli\u003eFine wire center electrode provides a focused spark for improved ignition.\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\u003eVendor Part Number: IU31A\u003c\/li\u003e\n \u003cli\u003eCenter Electrode Type: Fine Wire\u003c\/li\u003e\n \u003cli\u003eElectrode Tip Material: Iridium\u003c\/li\u003e\n \u003cli\u003eGround Electrode Shape: Angled, Grooved\u003c\/li\u003e\n \u003cli\u003eHeat Range: 31\u003c\/li\u003e\n \u003cli\u003eHex Size: 16 mm (5\/8\")\u003c\/li\u003e\n \u003cli\u003eSpark Gap: 0.9 mm\u003c\/li\u003e\n \u003cli\u003eThread Reach: 19,1 mm (3\/4\")\u003c\/li\u003e\n \u003cli\u003eThread Size: 10 mm\u003c\/li\u003e\n \u003cli\u003eType: Resistor\u003c\/li\u003e\n \u003cli\u003eElectrical Resistance: 5k Ohms\u003c\/li\u003e\n \u003cli\u003eCenter Electrode Projection: Non-Projected\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003eEnsure this spark plug is compatible with your vehicle's specifications before installation.
