When the cylinder head is torqued down, the rings slightly bite into the head gasket creating a mechanical barrier that prevents combustion pressure from leaking. This enhances head gasket reliability, particularly in high boost and high-horsepower builds.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eBlock machining is required; installation by a professional engine builder is advised.\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"5150 AutoSport","offers":[{"title":"Default Title","offer_id":53241261457715,"sku":null,"price":799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/3827\/3587\/files\/Set-of-8-Engine-Fire-Rings-for-BMW.webp?v=1740505553","url":"https:\/\/5150autosport.com\/products\/n63-s63-fire-ring-set","provider":"5150 AutoSport","version":"1.0","type":"link"}
