{"product_id":"kt-025-021-0310000","title":"DENSO DENSO Iridium Racing Plug IW01-31","description":"【Kitaco 025-021-0310000 DENSO Iridium Racing Plug IW01-31 Kitaco 025-021-0310000】\u003cbr\u003e\n \"Iridium Racing\" is an iridium plug specifically for racing, maximizing iridium performance.\u003cbr\u003e\n ●0.8mm square all-platinum ground electrode\u003cbr\u003e\n Compared to the nickel alloy traditionally used for spark plug ground electrodes, platinum has a higher melting point,\u003cbr\u003e\n reducing the risk of melting and wear of the ground electrode even under severe racing conditions.\u003cbr\u003e\n Additionally, a 0.8mm square platinum alloy is welded and formed into a gap without bending, resulting in no residual stress and improved durability. *Excluding RU01\u003cbr\u003e\n ●0.4mm diameter ultra-fine iridium center electrode\u003cbr\u003e\n By adopting the high-melting-point material \"new iridium alloy,\" the tip of the center electrode has been made ultra-fine, reducing spark voltage and significantly improving ignition performance. *Excluding RU01\u003cbr\u003e\n ●Flame cleaning pocket\u003cbr\u003e\n A small gap has been created all around the tip of the insulator clearance with the center electrode. This burns off carbon when the plug is fouled or covered, restoring insulation.\u003cbr\u003e\n ●Silicone oil coating\u003cbr\u003e\n For racing vehicles, fouling and carbon deposits before the start are critical. To prevent this,\u003cbr\u003e\n the water repellency of silicone on the insulator separates moisture and carbon from the insulator surface, preventing a drop in the plug's insulation performance.\u003cbr\u003e\n ●Chamfered housing end face\u003cbr\u003e\n The chamfer on the housing end face has been enlarged to improve resistance to abnormal combustion.\u003cbr\u003e\n This helps to cover even slight setting deviations.\u003cbr\u003e\n It also facilitates the discharge of residual gases and the influx of new gases, improving self-cleaning performance and making it resistant to fouling.\u003cbr\u003e\n ●0.8mm square all-platinum ground electrode\u003cbr\u003e\n Compared to the nickel alloy traditionally used for spark plug ground electrodes, platinum has a higher melting point,\u003cbr\u003e\n reducing the risk of melting and wear of the ground electrode even under severe racing conditions.\u003cbr\u003e\n Additionally, a 0.8mm square platinum alloy is welded and formed into a gap without bending, resulting in no residual stress and improved durability. *Excluding RU01\u003cbr\u003e\n ●0.4mm diameter ultra-fine iridium center electrode\u003cbr\u003e\n By adopting the high-melting-point material \"new iridium alloy,\" the tip of the center electrode has been made ultra-fine, reducing spark voltage and significantly improving ignition performance. *Excluding RU01\u003cbr\u003e\n ●Race-specific insulator\u003cbr\u003e\n A new reinforced insulator, developed through countless races, has been adopted, improving strength by approximately 20% compared to conventional insulators.\u003cbr\u003e\n ○Thread diameter: 14mm\u003cbr\u003e\n ○Reach: 19mm\u003cbr\u003e\n ○Hex size: 20.6mm\u003cbr\u003e\n ○Center electrode: Iridium\u003cbr\u003e\n ○Ground electrode: Tapered ground electrode \/ Platinum material\u003cbr\u003e\n ○Terminal: Attached (crimped)\u003cbr\u003e\n *Images are for illustration purposes only.
