To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to the material structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip. – Valve Tip Length 4.7mm – Stem Diameter 5.96mm.\u003c\/p\u003e\u003cp\u003e– Valve Length 114.75mm – Valve Head Size 0.020″ \/ 0.5mm – Valve Head Diameter 28.5mm – Valve Type Exhaust – Valve Stem Diameter 5.96mm – Valve Material Stainless Steel, Super Alloy Replaces OEM Part # 11-34-7-553-775 \/ 11 34 7 553 775 \/ 11347553775.\u003c\/p\u003e","brand":"navqelixo","offers":[{"title":"Default Title","offer_id":44564566212711,"sku":"YFLAR227360","price":75.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0689\/5910\/9223\/files\/ExhaustValves12_911d820e-1767-4b06-a32c-045b6e25af80.webp?v=1788628113","url":"https:\/\/navqelixo.shop\/products\/ferrea-competition-plus-exhaust-valve-kit-28-5mm-0-5mm-bmw-n54","provider":"navqelixo","version":"1.0","type":"link"}
