{"product_id":"ltr7ix-11-iridium-spark-plug-1","title":"LTR7IX-11 Iridium Spark Plug","description":"The NGK LTR7IX-11 (Stock No. 6510) is a high-performance spark plug engineered for demanding, high-tech engines. Its ultra-fine 0.6mm fine-wire iridium center electrode reduces voltage requirements, leading to faster starts, smoother idling, and improved throttle response. The iridium alloy's extremely high melting point ensures consistent performance even in high-compression or forced-induction environments.\n\nConstructed with a pure alumina silicate ceramic insulator and a solid copper core, these plugs maximize heat dissipation away from the combustion chamber. Trivalent metal plating offers superior anti-corrosion and anti-seizing properties, protecting cylinder heads and simplifying future plug changes. Corrugated ribs provide flashover protection, ensuring the spark occurs only at the electrode tip, while specialized triple seals prevent combustion gas leakage for maintained compression and peak power.\n\nThis spark plug is specifically designed for Gen V GM LT-series engines, including the LT1, LT4, LT5, L83, L86, and L8T. It is also noted as a one-step colder plug (higher heat range) for MZR DISI engines, commonly found in the Mazdaspeed 3, Mazdaspeed 6, and Mazda CX-7. The preset gap is 1.1mm (0.044\"), though users are advised to verify the gap for specific build requirements, especially in forced induction or nitrous applications.","brand":"NGK LTR7IX-11","offers":[{"title":"Default Title","offer_id":52663101227320,"sku":"NGK6510","price":8.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687073004.jpg?v=1784323821","url":"https:\/\/store.motormia.co\/products\/ltr7ix-11-iridium-spark-plug-1","provider":"MOTORMIA","version":"1.0","type":"link"}
