Constructed from multiple layers of steel with a special fluorine rubber coating, it's engineered for exceptional sealing under the heat and pressure of high-boost, high-horsepower applications.\u003c\/p\u003e\u003cp\u003eThe stopper-type design uses the maximum number of plate layers possible along with a molded stopper ring around each combustion chamber, while an independent bead design around the water and head bolt holes reduces overheat risk if gas leakage occurs and helps prevent cracking in the block. HKS bench-tested this gasket at 660PS, with real-world track testing confirmed at 600PS and 80kgm of torque. The kit includes matching exhaust manifold, intake manifold, and throttle body gaskets for a complete top-end reseal.\u003c\/p\u003e\u003cmeta name=\"description\" content=\"Upgrade your Nissan Skyline GT-R with the HKS 1.2mm Stopper Type Metal Head Gasket Kit for unmatched sealing and performance.\"\u003e\u003cmeta name=\"keywords\" content=\"HKS Stopper Type metal gasket, Nissan Skyline GT-R gasket, RB26DETT performance parts, high-boost head gasket, multi-layer metal gasket, automotive sealing technology, exhaust manifold gasket kit, intake manifold gasket, high-performance engine components, engine rebuild gasket set\"\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":53856567427391,"sku":"HKS23009-AN008","price":320.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/be1d8c67-c470-4af6-900a-b633cfa541cf-800.jpg?v=1782398912","url":"https:\/\/wcaperformance.com\/products\/hks-smg-k-set-rb26dett-t-1-2","provider":"WCA Performance","version":"1.0","type":"link"}
