{"product_id":"iridium-tt-spark-plug-10","title":"Iridium TT Spark Plug","description":"The Denso 4702 IK20TT Iridium TT spark plug combines advanced materials and design to deliver superior ignition performance and extended service life. Its innovative Twin-Tip (TT) technology features a fine wire 0.4mm iridium center electrode and a 0.7mm needle tip platinum ground electrode. This configuration concentrates spark energy, leading to more efficient combustion, improved acceleration, and better fuel economy. The high concentration of iridium in Denso's patented alloy ensures durability, with a rated lifespan exceeding 100,000 miles.\n\nConstructed for reliability, the IK20TT spark plug includes machine-rolled threads to prevent seizing and cross-threading, facilitating easier installation and removal. The purified alumina powder insulator provides exceptional strength and thermal conductivity, while a five-rib design prevents flashover. A copper-glass seal ensures a gas-tight connection between the center electrode and insulator, maintaining optimal performance.\n\nKey specifications include a 14mm thread diameter, 1.25mm thread pitch, and a 19mm reach. The plug is resistor-equipped for interference suppression and has a standard 0.039\" (1.0mm) gap, though it is pre-fired to ensure the highest quality. Denso recommends specific torque values for installation, with ranges provided for cast iron (26-30 lb. ft.) and aluminum (15-22 lb. ft.) cylinder heads.","brand":"Denso","offers":[{"title":"Default Title","offer_id":52687639544120,"sku":"IK20TT","price":10.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687895870.jpg?v=1784885732","url":"https:\/\/store.motormia.co\/products\/iridium-tt-spark-plug-10","provider":"MOTORMIA","version":"1.0","type":"link"}
