{"product_id":"hx-double-fine-electrode-projected-square-platinum","title":"HX Double Fine Electrode Projected Square Platinum","description":"The NGK 90495 Ruthenium HX spark plug is engineered with advanced high-ignitability technology to provide a more complete fuel burn compared to other precious metal spark plugs. This results in quicker throttle response, smoother idling, and improved cold starts, making it an ideal upgrade for modern engines demanding efficiency and performance.\n\nConstructed with a Ruthenium center electrode and a projected square platinum electrode (PSPE) on the ground electrode, this spark plug is built for maximum durability and performance, especially in high heat conditions typical of turbo and supercharged engines. It also features a copper core for reliable conductivity and a ceramic insulator for excellent heat dissipation. The spark plug has a J-Gap ground configuration, a non-removable nut electrical terminal type, and a M14-1.25 thread size with a 0.984 inch (25.0 mm) reach. The hex size is 5\/8\" (16mm).\n\nThis spark plug comes pre-gapped at 0.032\" (0.8 mm), but it is recommended to check and adjust the gap to within ±0.004\" of the OE-recommended value using a spark plug gap tool for optimal engine performance. Torque specifications vary depending on the cylinder head material: 10.8-18 lb. ft. for cast iron and 7.2-14.5 lb. ft. for aluminum.\n\nNGK's patented Ruthenium technology offers superior oxidation resistance and enhanced blistering\/anti-peeling properties, providing optimal durability even under demanding high-temperature driving conditions. This plug is designed to last between 60,000 to 120,000 miles. The part number for this specific Ruthenium HX plug is LTR6BHX.","brand":"NGK Ruthenium","offers":[{"title":"Default Title","offer_id":52663103586616,"sku":"NGK90495","price":9.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687077563.jpg?v=1784323843","url":"https:\/\/store.motormia.co\/products\/hx-double-fine-electrode-projected-square-platinum","provider":"MOTORMIA","version":"1.0","type":"link"}
