Upgrading the valves in your VW or Audi engine increases reliability with slow forging processes, upgraded aerospace alloys, CNC machining, and heat treatments to withstand extreme abuse from high-powered race engines and daily driven road vehicles making beyond factory power levels. The power an engine produces is limited to airflow. As the smallest chokepoint in your cylinder head, performance valves are engineered to increase airflow by limiting turbulence created by valve stem obstruction and careful detailing of the valve head and valve angles.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCOMPETITION PLUS VALVES (INTAKE)\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eFerrea's Competition Plus Intake Valve are reliable and extreme duty valve option for the 2.5L 20V engines for both N\/A or boosted applications. 2-step slow forged from special aerospace quality EV8-Z18 alloys eliminates material structural damage and provides proper grain flow with extremely reliable high-tensile strength. Each valve is heat-treated and stress-relieved over a 48-hour period for molecular integrity and feature avionics-quality hard chrome along with a specially applied hard tip.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSUPER ALLOY VALVES (EXHAUST)\u003c\/strong\u003e\u003cbr\u003eFerrea's Super Alloy exceeds typical Inconel alloy and is highly recommended for exhaust valves in turbocharged or boosted 2.5L 5 Cylinder engine builds. Super Alloy is the absolute highest level available in exhaust valve technology. Engineered to handle extreme heat requirements and punishment from turbocharged engines running high boost, nitro fuels, nitrous oxides, ethanol, and pump gas. Reversed forged for superior strength and durability, the Super Alloy can withstand exhaust gas temperatures exceeding 2400 degrees Fahrenheit onto the valve. Every valve is finished with a refined swirl and micro polish to eliminate surface imperfections. Ferrea's valves have been used in Top Fuel and Funny Car applications and can confirm the performance and reliability of Super Alloy Valves in the most demanding and volatile situations. Put that same level of reliability in your own 2.5L 20V engine build.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVALVE TECHNICAL SPECS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"bullet\"\u003e\n\u003cli\u003eCompetition Plus Intake Valves\u003c\/li\u003e\n\u003cli\u003eHead Diameter: 32.35mm (33.35mm oversize available)\u003c\/li\u003e\n\u003cli\u003eStem Diameter: 5.98mm\u003c\/li\u003e\n\u003cli\u003eOverall Length: 104mm\u003c\/li\u003e\n\u003cli\u003eTip Length: 5mm\u003c\/li\u003e\n\u003cli\u003eTriple-groove stems (reuse stock valve keepers)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSuper Alloy Exhaust Valves\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"bullet\"\u003e\n\u003cli\u003eHead Diameter: 28mm (29mm oversize available)\u003c\/li\u003e\n\u003cli\u003eStem Diameter: 5.97mm\u003c\/li\u003e\n\u003cli\u003eOverall Length: 102mm\u003c\/li\u003e\n\u003cli\u003eTip Length: 5mm\u003c\/li\u003e\n\u003cli\u003eTriple-groove stems(reuse stock valve keepers)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVEHICLE FITMENT BY ENGINE?\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAudi - 2.5T 20V 5 Cylinder Turbo Engines\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTTRS 2008-2015 (MK2 - 8J) 2.5T engines\u003c\/li\u003e\n\u003cli\u003eTTRS 2017+ (MK3 - 8V) 2.5T engines\u003c\/li\u003e\n\u003cli\u003eRS3 2008-2015 (MK2 - 8J) 2.5T engines\u003c\/li\u003e\n\u003cli\u003eRS3 2017+ (MK3 - 8V) 2.5T engines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVW - 2.5L 20V 5 Cylinder Engines\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVW - Rabbit 2006-2009 (MK5) 2.5L engines\u003c\/li\u003e\n\u003cli\u003eVW - Golf 2010-2014 (MK6) 2.5L engines\u003c\/li\u003e\n\u003cli\u003eVW - Jetta \u0026amp; Jetta GLI 2006-2010 (MK5) 2.5L engines\u003c\/li\u003e\n\u003cli\u003eVW - Jetta \u0026amp; Jetta GLI 2010-2014 (MK6) 2.5L engines\u003c\/li\u003e\n\u003cli\u003eVW - Jetta SportWagen 2011-2014 (MK6) 2.5L engines\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Valvetrain","offers":[{"title":"yes","offer_id":43533362725052,"sku":"FER-F2417P\u002619P-10Y","price":2925.0,"currency_code":"AUD","in_stock":true},{"title":"no","offer_id":44117255225532,"sku":"FER-F2417P\u002619P-10N","price":2750.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/3128\/3644\/files\/1_68934578-32b5-4a8e-aece-040250e42593.jpg?v=1726036084","url":"https:\/\/www.jdyperformance.com.au\/products\/ferrea-intake-and-exhaust-valves-and-valve-spring-kits-for-2-0t-fsi-gen-1-2-tsi","provider":"JDY Performance AU","version":"1.0","type":"link"}
