{"product_id":"bougie-ngk-mr8bi-8-iridium","title":"MR8BI-8 Iridium","description":"Essential for providing the best possible spark to ensure optimal combustion of the air-fuel mixture in the engine cylinders while helping to dissipate the heat from the explosion of this mixture, motorcycle spark plugs should be replaced every +\/- 10,000 kilometers, at regular intervals. \u003cbr\u003eTheir replacement may be necessary earlier if your motorcycle engine is not running properly.\u003cbr\u003e\u003cbr\u003eA worn spark plug can cause ignition, combustion, and pre-ignition issues, increase fuel consumption, and reduce the power of the motorcycle...\u003cbr\u003e \u003cbr\u003eThere are 2 types of spark plugs: hot plugs and cold plugs. They are distinguished based on their thermal dissipation index, coded by a number on the plug. \u003cbr\u003e\u003cbr\u003eHot plugs have a low thermal dissipation index (low number), perfect for road riding.\u003cbr\u003eCold plugs have a high thermal dissipation index (high number), perfect for sport riding.\u003cbr\u003e\u003cbr\u003eThus, the performance of your motorcycle depends on them, both in terms of starting, engine efficiency, and fuel consumption.\u003cbr\u003e\u003cbr\u003eNGK, one of the market leaders, produces the most advanced and technologically suitable spark plugs for modern engines.\u003cbr\u003e\u003cbr\u003eDiscover the reliability of the NGK MR8BI-8 Iridium motorcycle spark plug, made with precious metal, offering optimal lifespan. The tapered shape of its electrode ensures a larger flame propagation compared to a standard spark plug. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eNGK MR8BI-8 Iridium motorcycle spark plug\u003c\/li\u003e\n\u003cli\u003eCentral electrode made of iridium (a precious metal and one of the strongest in the world)\u003c\/li\u003e\n\u003cli\u003eThe lifespan of an iridium spark plug is twice that of a standard spark plug\u003c\/li\u003e\n\u003cli\u003eThermal dissipation index: 8\u003c\/li\u003e\n\u003cli\u003eIntegrated 5 K0hm resistor\u003c\/li\u003e\n\u003cli\u003eHex: long\u003c\/li\u003e\n\u003cli\u003eThread diameter: 10 mm\u003c\/li\u003e\n\u003cli\u003eThread length: 19.1 mm\u003c\/li\u003e\n\u003cli\u003eElectrode gap: 0.8 mm\u003c\/li\u003e\n\u003cli\u003eWrench size to use: 16 mm\u003c\/li\u003e\n\u003cli\u003eSpark plug sold individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003c\/ul\u003e","brand":"NGK","offers":[{"title":"Accessory","offer_id":52777861087579,"sku":"52006-8-65","price":29.52,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/3227\/1195\/files\/bougie-ngk-mr8bi-8-iridium-s6.jpg?v=1792748308","url":"https:\/\/icasque.com\/en-uk\/products\/bougie-ngk-mr8bi-8-iridium","provider":"iCasque","version":"1.0","type":"link"}
