{"product_id":"ltr7ix-11-iridium-ix-spark-plug-1","title":"LTR7IX-11 Iridium IX Spark Plug","description":"The NGK LTR7IX-11 Iridium IX spark plug serves as a 1-step colder upgrade for performance applications, helping to prevent engine knock and detonation in high-heat or forced induction environments. Its design utilizes an iridium alloy center electrode with an extremely high melting point, which is six times harder than platinum for enhanced long-term durability.\n\nTechnical specifications include a 25mm reach, a 5\/8-inch (16mm) hex size, a solid terminal, and a factory-set gap of .043 inches (1.1mm). This part does not require an EO in California and is legal for sale and use in all 50 states.\n\nInstallation considerations: While the plugs come pre-gapped, some performance applications may require manual adjustment of the gap based on specific engine tuning or forced induction requirements. Note that NGK has a recommended limit on the amount of bending allowed for the ground electrode when adjusting the gap. Proper fitment is verified for 2011-2017 Ford Mustang and 2012-2013 Boss Mustang models; verify exact compatibility for your specific engine and forced induction setup before installation.","brand":"NGK 1-Step","offers":[{"title":"Default Title","offer_id":52663101292856,"sku":"LTR7IX-11 (6510)","price":10.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687077222.jpg?v=1784323822","url":"https:\/\/store.motormia.co\/products\/ltr7ix-11-iridium-ix-spark-plug-1","provider":"MOTORMIA","version":"1.0","type":"link"}
