{"product_id":"conventional-spark-plug","title":"Conventional Spark Plug","description":"The ACDelco R45S is a professional-grade conventional spark plug engineered to deliver reliable performance and efficient operation. Its design incorporates a copper-core center electrode, which enhances heat transfer to the tip, helping to prevent low-speed carbon fouling. This construction, combined with a hot-tip insulator, ensures the plug heats rapidly and maintains a hot operating temperature for optimal firing.\n\nConstructed with a nickel-chrome alloy on both the ground electrode and the center electrode sheathing, the R45S is built to withstand the harsh conditions of the combustion chamber. This material resists wear caused by spark erosion and corrosive elements, contributing to the plug's durability and lifespan. The spark plug features a gasket seat type and a pre-set gap of 0.040 inches, with specifications including a 13\/16\" hex size, 0.37\" reach, and 14mm thread diameter.\n\nAs part of ACDelco's Gold (Professional) line, these spark plugs are manufactured to meet GM's high standards for fit, form, and function, offering a quality aftermarket alternative to Original Equipment parts. They are suitable for a variety of marine applications and are backed by a 24 Months\/Unlimited Miles Limited Warranty.","brand":"ACDelco","offers":[{"title":"Default Title","offer_id":52686749139256,"sku":"R45S","price":1.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660671151.jpg?v=1784876284","url":"https:\/\/store.motormia.co\/products\/conventional-spark-plug","provider":"MOTORMIA","version":"1.0","type":"link"}
