{"product_id":"iridium-tt-spark-plug-2","title":"Iridium TT Spark Plug","description":"The Denso IKBH20TT Iridium TT spark plug combines advanced materials and manufacturing processes to deliver superior performance and an extended lifespan of over 100,000 miles. Its unique Twin-Tip (TT) technology, featuring the world's smallest 0.4mm iridium center electrode and a 0.7mm needle-tip ground electrode, is engineered to concentrate spark energy, leading to improved acceleration, power, and fuel economy.\n\nConstructed with Denso's patented iridium alloy, known for its high concentration and durability, these spark plugs ensure a dramatic improvement in service life. The 360-degree laser welding process further contributes to their robustness. For ease of installation and to prevent seizing or cross-threading, the spark plugs feature machine-rolled threads. Each plug is 100% pre-fired to guarantee the highest quality.\n\nThe design also incorporates a purified alumina powder insulator for exceptional strength and thermal conductivity, along with a five-rib insulator to prevent flashover. A copper-glass seal ensures a gas-tight connection between the center electrode and the insulator, maintaining optimal performance and reliability.\n\nKey specifications include a 14mm thread diameter, 1.25mm thread pitch, 26.5mm reach, and a 5\/8\" (16mm) hex size. The center electrode is fine wire iridium, while the ground electrode is a hybrid platinum with three prongs. These spark plugs are resistor-type with a 5k Ohm value.\n\nFitment includes numerous Lexus and Toyota models from 2019 to 2023, such as various trims of the Lexus ES350, IS300\/350, LC500, and RC models, as well as Toyota Camry and Tacoma variants. It is crucial to verify fitment for your specific vehicle's year, make, model, and engine.","brand":"Denso Iridium","offers":[{"title":"Default Title","offer_id":52687633318200,"sku":"IKBH20TT","price":13.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664702963.jpg?v=1784885711","url":"https:\/\/store.motormia.co\/products\/iridium-tt-spark-plug-2","provider":"MOTORMIA","version":"1.0","type":"link"}
