{"product_id":"iridium-tt-spark-plug-6","title":"Iridium TT Spark Plug","description":"The Denso Iridium TT spark plug combines advanced technologies for superior performance and extended service life. It utilizes a unique Twin-Tip (TT) design featuring the world's smallest 0.4mm iridium center electrode and a 0.7mm needle tip ground electrode. This configuration promotes concentrated spark energy, leading to improved acceleration, increased power, enhanced torque, and better fuel economy by minimizing spark interference and maximizing ignitability.\n\nConstructed with Denso's patented iridium alloy, known for its high concentration and durability, the Iridium TT spark plug boasts a lifespan exceeding 100,000 miles. The center electrode is secured using Denso’s 360-degree laser welding process, ensuring reliability. Additionally, machine-rolled threads prevent seizing or cross-threading during installation and removal, while a purified alumina powder insulator provides exceptional strength and thermal conductivity. A five-rib insulator design prevents flashover, and a copper-glass seal ensures a gas-tight connection between the center electrode and the insulator.\n\nThis spark plug is 100% pre-fired to guarantee the highest quality. Key specifications include a 14mm thread diameter, 1.25mm thread pitch, gasket seat type, 19mm reach, 5\/8\" (16mm) hex size, and a solid terminal type. It is designed as a resistor plug with a 5k Ohm resistor value and has a heat range of 20. Torque specifications are provided for both cast iron (26-30 lb. ft.) and aluminum (15-22 lb. ft.) cylinder heads.","brand":"Denso Iridium","offers":[{"title":"Default Title","offer_id":52687636758840,"sku":"IK20TT","price":10.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662653753.jpg?v=1784885720","url":"https:\/\/store.motormia.co\/products\/iridium-tt-spark-plug-6","provider":"MOTORMIA","version":"1.0","type":"link"}
