{"product_id":"iridium-tt-spark-plug-7","title":"Iridium TT Spark Plug","description":"The Denso Iridium TT spark plug (IKH20TT) is engineered to deliver superior longevity and performance, boasting a lifespan of over 100,000 miles. Its innovative Twin-Tip (TT) technology combines a fine 0.4mm iridium center electrode with a 0.7mm platinum-tipped ground electrode, both secured by Denso's 360-degree laser welding. This design minimizes spark interference and maximizes ignitability, resulting in a more concentrated spark that promotes improved acceleration and fuel efficiency.\n\nConstructed with a patented iridium alloy for maximum durability, the Iridium TT features a purified alumina powder insulator for exceptional strength and thermal conductivity, preventing flashover with its five-rib design. Machine-rolled threads ensure easy installation and removal without cross-threading or seizing. Each plug is 100% pre-fired to guarantee the highest quality.\n\nKey specifications include a 14mm thread diameter, 1.25mm thread pitch, 26.5mm reach, and a 5\/8\" (16mm) hex size. The spark gap is set at .039\" (1.0mm), and it incorporates a 5k Ohm resistor. Recommended torque specifications are 26-30 lb. ft. for cast iron cylinder heads and 15-22 lb. ft. for aluminum.","brand":"Denso Iridium","offers":[{"title":"Default Title","offer_id":52687636922680,"sku":"IKH20TT","price":10.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687895855.jpg?v=1784885723","url":"https:\/\/store.motormia.co\/products\/iridium-tt-spark-plug-7","provider":"MOTORMIA","version":"1.0","type":"link"}
