On an average plug, a narrow core typically shortens life span of plug but with the intense durability of iridium there is no sacrifice in any longevity. With a high melting point of 2454 degrees C, opposed to the 1769 degrees C of white gold, the electrode can tolerate the high levels of compression and minor knocking without any deterioration. A nickel coating on the housing also prevents the spark plug from premature deterioration. The Iridium plugs are available for multiple applications and offered in colder heat ranges of 7 and up and specifically for rotary, heat ranges of 9 and up are offered.\u003c\/div\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":45621734801571,"sku":"50003-M40XL","price":26.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/9336\/9763\/files\/HKS_M-SERIES_SPARK_PLUG.jpg?v=1739902765","url":"https:\/\/www.jdmpurist.com\/products\/hks-m-series-spark-plug","provider":"JDM Purist","version":"1.0","type":"link"}
