{"product_id":"ltr7ix-11-iridium-spark-plug","title":"LTR7IX-11 Iridium Spark Plug","description":"The NGK LTR7IX-11 (Stock No. 6510) is a high-performance spark plug engineered specifically for GM Gen V LT engines, including LT1, LT4, LT5, L83, L86, and L8T applications. These plugs are constructed with a 0.6mm fine-wire iridium center electrode that reduces voltage requirements, promoting faster starts, smoother idling, and enhanced throttle response. The iridium alloy offers a high melting point, making these a preferred choice for enthusiasts running modified or high-output engines.\n\nTechnical features include trivalent metal plating for superior anti-corrosion and anti-seizing properties, corrugated ribs to prevent electrical flashover, and a pure alumina silicate ceramic insulator coupled with a solid copper core for efficient heat dissipation. A gas-tight triple seal design helps maintain combustion chamber pressure and peak performance under extreme conditions.\n\nThese spark plugs are classified with a heat range of 7, which is one step colder than most stock LT1\/LT4 applications. They feature a tapered seat, a 5\/8-inch hex size, and a preset gap of 0.044 inches. While they are pre-gapped, users must verify the gap for their specific build requirements, particularly when utilizing forced induction or nitrous systems. Always ensure correct torque specifications during installation to protect cylinder heads.","brand":"NGK 6510","offers":[{"title":"Default Title","offer_id":52663100408120,"sku":"NGK-6510-8PK","price":6.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687077226.jpg?v=1784323814","url":"https:\/\/store.motormia.co\/products\/ltr7ix-11-iridium-spark-plug","provider":"MOTORMIA","version":"1.0","type":"link"}
