The kit is designed to be used on the base 5.0L Ti-VCT head.\n\nThis valve spring kit is original equipment for the 2012-2013 Mustang Boss 302 and is also a direct fit for 2011-2014 Mustang GT models equipped with the 5.0L engine. Installation may require specialized tools such as a valve spring compressor and height micrometer, which are sold separately.","brand":"Boss","offers":[{"title":"Default Title","offer_id":52687229616440,"sku":"M-6513-M50BR","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662155482.jpg?v=1784881649","url":"https:\/\/store.motormia.co\/products\/302r-valve-spring-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
