{"product_id":"iridium-tt-spark-plug-8","title":"Iridium TT Spark Plug","description":"The Denso 4705 IKBH20TT Iridium TT spark plug combines iridium and platinum technologies for a lifespan exceeding 100,000 miles. Its unique Twin-Tip (TT) design, featuring a 0.4mm iridium center electrode and a 0.7mm needle tip ground electrode, concentrates spark energy for improved acceleration and fuel economy. This design also maximizes ignitability by minimizing spark interference, leading to better power and torque.\n\nConstructed with a purified alumina powder insulator for strength and thermal conductivity, this spark plug also features a five-rib design to prevent flashover and a copper-glass seal for a gas-tight bond between the center electrode and insulator. Machine-rolled threads prevent seizing or cross-threading during installation and removal, and the plug is 100% pre-fired for quality assurance.\n\nSpecifications include a 14mm thread diameter, 1.25mm thread pitch, gasket seat type, 26.5mm reach, and a 16mm hex size. It is a solid terminal type with a 1.0mm gap and incorporates a resistor. Torque specifications are provided for cast iron (26-30 lb. ft.) and aluminum (15-22 lb. ft.) cylinder heads.","brand":"DENSO","offers":[{"title":"Default Title","offer_id":52687637872952,"sku":"IKBH20TT","price":13.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687895865.jpg?v=1784885726","url":"https:\/\/store.motormia.co\/products\/iridium-tt-spark-plug-8","provider":"MOTORMIA","version":"1.0","type":"link"}
