{"product_id":"laser-iridium-spark-plug-13","title":"Laser Iridium Spark Plug","description":"The NGK SILZBR8D8S Laser Iridium spark plug is engineered as a \"one-step colder\" replacement for specific BMW M series vehicles equipped with N55 or S55 engines. This design choice is intended to help manage higher combustion temperatures in performance applications. It features a fine wire iridium center electrode and a fine wire platinum ground electrode, contributing to a slow wear rate, stable idle, improved fuel efficiency, and reduced emissions.\n\nThe plug's shell is treated with trivalent metal plating for enhanced anti-corrosion and anti-seizing capabilities, and corrugated ribs are incorporated to prevent flashover. Triple seals are employed to ensure a leak-free installation.\n\nThis spark plug is specifically listed for fitment on the 2015-2018 BMW M3 F80 S55, 2015-2020 BMW M4 F82\/F83 S55, 2019-2021 BMW M2 F87 Competition S55, and 2016-2018 BMW M2 F87 N55.\n\nInstallation requires a specialized Thin-Walled 14mm 12-Point Tool Spark Plug Socket Tool for the N55\/S55 engines. The recommended torque specification for aluminum S55\/N55 blocks is 10.8-14.5 ft-lb.","brand":"NGK","offers":[{"title":"Default Title","offer_id":52663099556152,"sku":"SILZBR8D8S","price":17.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687072625.jpg?v=1784323806","url":"https:\/\/store.motormia.co\/products\/laser-iridium-spark-plug-13","provider":"MOTORMIA","version":"1.0","type":"link"}
