Manufactured by DENSO, this spark plug uses a fine iridium center electrode that requires less voltage to produce a strong, consistent spark. Its design supports efficient combustion and reliable starting across a broad range of operating conditions.\u003c\/p\u003e\u003cp\u003eIridium is significantly harder and more heat-resistant than conventional spark plug materials, withstanding temperatures up to 4,000°F. The 360-degree laser-welded electrode construction creates a secure seal designed to resist wear, while the tapered-cut ground electrode and U-groove promote a larger flame-kernel area for more complete ignition. These features help maintain stable performance in high-temperature and high-stress environments.\u003c\/p\u003e\u003cp\u003eDesigned for applications requiring the DENSO IX24B specification, this plug should be matched to the vehicle or equipment manufacturer’s recommended heat range, thread, reach, and ignition requirements before installation. It is suitable as a replacement spark plug where DENSO part number 5376 is specified. Verify fitment using the application catalog or the original spark plug specifications to ensure proper compatibility.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e DENSO\u003cbr\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e IX24B\u003cbr\u003e\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 5376\u003cbr\u003e\u003cstrong\u003eVendor Part Number:\u003c\/strong\u003e 5376\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIridium Electrode: Fine 0.4 mm center electrode helps reduce voltage requirements and improve firing performance.\u003c\/li\u003e\n\u003cli\u003eHigh-Temperature Resistance: Iridium construction withstands temperatures up to 4,000°F for demanding engine conditions.\u003c\/li\u003e\n\u003cli\u003eLaser-Welded Construction: 360-degree laser welding provides a sealed electrode assembly designed to resist wear.\u003c\/li\u003e\n\u003cli\u003eEnhanced Flame Development: Tapered-cut ground electrode and U-groove create a larger flame-kernel area for reliable ignition.\u003c\/li\u003e\n\u003cli\u003eApplication Fitment: Designed for vehicles and equipment specifying the DENSO IX24B spark plug, manufacturer part number 5376.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DENSO","offers":[{"title":"Default Title","offer_id":67567394357483,"sku":"IX24B","price":16.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/34905.png?v=1790796301","url":"https:\/\/ctracingservices.com\/products\/denso-iridium-spark-plug-ix24b-part-number-5376","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
