Until recently, this OE iridium Twin-Tip design could only be found in the most technologically advanced automobiles. But now DENSO is offering this cutting-edge technology in a brand new platinum\/titanium design customized for today’s value-minded automotive enthusiasts. DENSO pioneered the use of platinum in spark plug manufacturing. To maximize the longevity and enhance the durability of the spark plug, DENSO applied platinum to both the center and ground electrodes. Platinum offers superior resistance to erosion and corrosion enabling DENSO to create a spark plug capable of consistent performance.\u003c\/p\u003e\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1.1 millimeter platinum center electrode\u003c\/li\u003e\n\u003cli\u003eTitanium-enhanced alloy ground electrode\u003c\/li\u003e\n\u003cli\u003eMinimum-Quench Electrode Design\u003c\/li\u003e\n\u003cli\u003eImproved fuel economy and faster starts\u003c\/li\u003e\n\u003cli\u003eEnhanced flame propagation for increased engine efficiency\u003c\/li\u003e\n\u003cli\u003eFree standing firing pad reduces quenching to generate a more powerful spark\u003c\/li\u003e\n\u003cli\u003eMachine rolled threads prevent seizing or cross threading during installation and removal\u003c\/li\u003e\n\u003cli\u003e100 percent pre-fired to assure the highest quality possible\u003c\/li\u003e\n\u003cli\u003ePurified alumina powder insulator provides exceptional strength and thermal conductivity\u003c\/li\u003e\n\u003cli\u003eLimited 1 year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eMinimum-Quench Electrode Design\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003e1.1 millimeter platinum center electrode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eTitanium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.2 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e4 x 2 x 1 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eDenso\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number\u003c\/td\u003e\n\u003ctd\u003e4503\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e042511045033\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cstyle\u003e\n.product-faq { margin: 2rem 0; }\n.product-faq__title { font-size: 1.25rem; margin-bottom: 1rem; }\n.faq-item { border: 1px solid #ddd; border-radius: 4px; margin-bottom: 0.5rem; }\n.faq-item__question { padding: 0.75rem 1rem; font-weight: 600; cursor: pointer; }\n.faq-item__answer { padding: 0 1rem 0.75rem; }\ndetails.faq-item \u003e summary { list-style: none; }\ndetails.faq-item \u003e summary::-webkit-details-marker { display: none; }\n.related-items-table { width: 100%; border-collapse: collapse; margin: 1rem 0; }\n.related-items-table th, .related-items-table td { border: 1px solid #ddd; padding: 0.5rem; text-align: left; vertical-align: top; }\n.related-items-table th { background: #f7f7f7; }\n\u003c\/style\u003e\u003csection class=\"product-faq\" aria-label=\"Frequently asked questions\"\u003e\u003ch2 class=\"product-faq__title\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails class=\"faq-item\"\u003e\u003csummary class=\"faq-item__question\"\u003eHow do I verify fitment before ordering?\u003c\/summary\u003e\u003cdiv class=\"faq-item__answer\"\u003e\u003cp\u003eCompare manufacturer part number 4503 against your existing part and your vehicle or equipment.
