Manufactured by Denso, a trusted original equipment supplier, this spark plug ensures optimal combustion and efficient operation, improving overall engine performance and fuel economy.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Denso W27ESRU spark plug features a copper core center electrode that provides superior thermal conductivity, efficiently dissipating heat and preventing overheating. The unique five-rib insulator design reduces flashover and minimizes voltage loss, ensuring a consistent and powerful spark. Its dual copper and glass seal creates a gas-tight bond between the center electrode and insulator, preventing leaks and maintaining optimal compression. The U-Groove ground electrode enhances ignitability, leading to improved combustion efficiency and reduced emissions. This resistor-type spark plug is designed for dependable performance in demanding conditions and is an excellent choice for enthusiasts and professionals alike. With a 14 mm thread size and 19.1 mm (3\/4\") thread reach, installation is straightforward and ensures a secure fit.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003eEnhanced thermal conductivity with copper core center electrode.\u003c\/li\u003e\n \u003cli\u003eReduced flashover and voltage loss with unique five-rib insulator.\u003c\/li\u003e\n \u003cli\u003eGas-tight seal with dual copper and glass construction.\u003c\/li\u003e\n \u003cli\u003eImproved ignitability with U-Groove ground electrode design.\u003c\/li\u003e\n \u003cli\u003eReliable performance in demanding conditions.\u003c\/li\u003e\n \u003cli\u003eMaintains optimal compression for consistent combustion.\u003c\/li\u003e\n \u003cli\u003eDesigned for efficient heat dissipation and long life.\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: W27ESR-U\u003c\/li\u003e\n \u003cli\u003eElectrode Tip Material: Nickel Alloy\u003c\/li\u003e\n \u003cli\u003eCenter Electrode Type: Standard\u003c\/li\u003e\n \u003cli\u003eCenter Electrode Projection: Non-Projected\u003c\/li\u003e\n \u003cli\u003eGround Electrode Shape: U-Groove\u003c\/li\u003e\n \u003cli\u003eHeat Range: 27\u003c\/li\u003e\n \u003cli\u003eHex Size: 20.6 mm (13\/16\")\u003c\/li\u003e\n \u003cli\u003eSpark Gap: 0.7 mm\u003c\/li\u003e\n \u003cli\u003eTerminal Configuration: Threaded Stud\u003c\/li\u003e\n \u003cli\u003eThread Reach: 19.1 mm (3\/4\")\u003c\/li\u003e\n \u003cli\u003eThread Size: 14 mm\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\u003eEnsure that the Denso W27ESRU spark plug is the correct fitment for your specific engine.
