{"product_id":"focus-st-calibration-and-spark-plug-kit","title":"Focus ST Calibration and Spark Plug Kit","description":"This 50-state legal upgrade includes the ProCal3 tool, a calibration tune, and performance spark plugs, designed to make your driving experience more exciting with greater torque and an improved interior sound.\n\nThis kit delivers noticeable power gains, providing up to a 90 ft-lbs of torque increase at 2800 rpm when using 93 octane fuel. The improved torque is felt throughout the RPM range, up to 4200 rpm, enhancing acceleration for track launches and spirited driving on winding roads. Additionally, the calibration revises the sound symposer software to provide a more natural and engaging engine sound within the cabin.\n\nInstallation requires a Windows laptop with internet access, as the tune is installed via the included ProCal3 tool. Premium fuel, specifically 91 octane or higher (93 octane recommended), is required to prevent spark knock or detonation under certain operating conditions. When installed by a Ford or Lincoln dealer or an ASE certified technician, this kit is eligible for a limited warranty.","brand":"Ford Performance","offers":[{"title":"Default Title","offer_id":52664207376696,"sku":"M-14204-FST","price":260.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687137489.jpg?v=1784335171","url":"https:\/\/store.motormia.co\/products\/focus-st-calibration-and-spark-plug-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
