These valves have been designed using advanced 3D design and simulation programs to create a stronger and higher flowing valve head design. Prototypes were used in specific applications to make sure that they have the highest flowing valve head that is available on the market today. The materials used have less valve distortion at the face than any of the tested designs which allows for better sealing under extreme conditions to promote more consistent performance throughout the life of the valve. \u003c\/p\u003e","brand":"GSC PowerDivision","offers":[{"title":"Default Title","offer_id":45712938729558,"sku":"GSC2014-8","price":46.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/0411\/1190\/files\/3tb0hdk2ta8l_de36f431-e807-48e3-9706-794c55b01495.jpg?v=1788786085","url":"https:\/\/truegearus.com\/products\/gsc-power-division-stainless-steel-intake-valves-1mm-subaru-models-inc-2002-2014-wrx-2004-2021-sti-su87s9","provider":"TrueGear","version":"1.0","type":"link"}
