Engineered for high-boost, high-performance applications, these oversized exhaust valves offer exceptional thermal stability, durability, and consistent performance under extreme conditions.\u003c\/p\u003e\n\n\u003cp\u003eCrafted from premium nickel-based superalloys (Inconel 751\/600 series), ZRP exhaust valves maintain their structural integrity at exhaust gas temperatures exceeding 800°C. They are specifically developed for extreme operating environments where standard stainless steel valves fail to withstand the required thermal and mechanical loads.\u003c\/p\u003e\n\n\u003cp\u003eThe +1.0mm oversized valve head enhances exhaust flow, making them ideal for upgraded turbo setups, ported cylinder heads, and high-performance builds focused on maximum efficiency and power. Each valve is precision CNC machined, swirl-polished, and heat-treated to ensure superior dimensional accuracy, a flawless surface finish, and high resistance to thermal fatigue. Strict tolerances for stem straightness, concentricity, and sealing surfaces guarantee reliable combustion sealing and stable operation at high RPMs. Technical Features\u003c\/p\u003e\n\n\u003cp\u003eMaterial: Nickel-based superalloy (Inconel 751 \/ 600 series)\u003c\/p\u003e\n\n\u003cp\u003eOversize: +1.0mm valve head diameter\u003c\/p\u003e\n\n\u003cp\u003eHeat Resistance: Maintains strength above 800°C\u003c\/p\u003e\n\n\u003cp\u003eManufacturing Process: Precision CNC machining, swirl polishing, and heat treatment\u003c\/p\u003e\n\n\u003cp\u003eDimensional Accuracy: Strict straightness and concentricity tolerances\u003c\/p\u003e\n\n\u003cp\u003eAdvantages\u003c\/p\u003e\n\n\u003cp\u003eIncreased exhaust flow potential\u003c\/p\u003e\n\n\u003cp\u003eReduced stem-to-guide friction\u003c\/p\u003e\n\n\u003cp\u003eExtended lifespan compared to stainless steel valves\u003c\/p\u003e\n\n\u003cp\u003eReliable sealing in high-performance turbocharged engines\u003c\/p\u003e\n\n\u003cp\u003eSuitable for track, endurance, and high-power builds\u003c\/p\u003e\n\n\u003cp\u003eAdditional Information\u003c\/p\u003e\n\n\u003cp\u003eSet Quantity: 12 valves\u003c\/p\u003e\n\n\u003cp\u003eMaterial: Inconel\u003c\/p\u003e\n\n\u003cp\u003eValve Size: 29.00mm (+1.0mm) \/ 5.96mm \/ 101.75mm\u003c\/p\u003e\n\n\u003cp\u003eEngine: Audi RS4 \/ RS5 3.0L Twin-Turbo Quattro EA839\u003c\/p\u003e","brand":"ZRP","offers":[{"title":"Default Title","offer_id":56965547327828,"sku":"VE-AUD-007-12","price":646.14,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1027\/4701\/3460\/files\/VE-AUD-007-12_d12a2f22-847b-4daf-ba9d-ff333760518b.jpg?v=1788489289","url":"https:\/\/www.thetunerlab.com\/en\/products\/valvulas-de-escape-zrp-10-mm-de-inconel-para-audi-vw-volkswagen-3-0l-twin-turbo-rs4-rs5-ea839","provider":"Thetunerlab","version":"1.0","type":"link"}
