Designed to withstand extreme exhaust temperatures and high cylinder pressures, these oversized exhaust valves offer exceptional strength, thermal stability, and long-term reliability in demanding street and racing applications.\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. Developed for heavy-duty use, they are ideal for high-boost turbocharged engines, upgraded cylinder heads, and endurance racing environments where conventional stainless steel valves are no longer sufficient. Each valve is precision CNC machined, swirl polished, and heat-treated to ensure excellent dimensional accuracy, an impeccable 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 Specifications\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 at exhaust gas temperatures exceeding 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 tolerances for stem straightness, concentricity, and sealing surfaces\u003c\/p\u003e\n\n\u003cp\u003eAdvantages\u003c\/p\u003e\n\n\u003cp\u003eIncreased exhaust flow potential due to larger valve head\u003c\/p\u003e\n\n\u003cp\u003eReduced stem-to-guide friction for less wear and improved high-RPM stability\u003c\/p\u003e\n\n\u003cp\u003eSignificantly extended lifespan compared to untreated stainless steel valves\u003c\/p\u003e\n\n\u003cp\u003eReliable sealing in high-performance turbocharged applications\u003c\/p\u003e\n\n\u003cp\u003eDesigned for motorsport, drag, and endurance racing vehicles\u003c\/p\u003e\n\n\u003cp\u003eAdditional Information\u003c\/p\u003e\n\n\u003cp\u003eSet Quantity: 10 Valves\u003c\/p\u003e\n\n\u003cp\u003eMaterial: Inconel\u003c\/p\u003e\n\n\u003cp\u003eValve Size: 29.00mm head (+1.0mm) \/ 5.96mm stem \/ 101.75mm length\u003c\/p\u003e\n\n\u003cp\u003eEngine Codes: DAZA, DNWA\u003c\/p\u003e\n\n\u003cp\u003eApplication: 2.5L TFSI EA855 – Audi TT-RS, RS3\u003c\/p\u003e","brand":"ZRP","offers":[{"title":"Default Title","offer_id":56965705400660,"sku":"VE-AUD-007-10","price":538.45,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1027\/4701\/3460\/files\/VE-AUD-007-10_fb20f007-b195-4f23-8691-38ba7f3d0554.jpg?v=1788663163","url":"https:\/\/www.thetunerlab.com\/en\/products\/valvulas-de-escape-zrp-10-mm-de-inconel-para-audi-vw-volkswagen-2-5l-tfsi-tt-rs-rs3-ea855","provider":"Thetunerlab","version":"1.0","type":"link"}
