JDY Performance Kelford Valvetrain Kit – 2.0T/FSI

Complete High-Performance Valvetrain Solution The JDY Performance Kelford Valvetrain Kit is a fully integrated upgrade package designed for high-performance EA888 engines operating under increased boost, elevated RPM, and extreme cylinder pressures. This kit combines Kelford’s precision-engineered beehive valve springs and stainless performance valves with Supertech valve stem seals, delivering a balanced and reliable valvetrain system for both street and race applications. What’s Included Kelford Beehive Valve Spring Set (KVS276-BT) Kelford Intake Valve Set Kelford Exhaust Valve Set Supertech Valve Stem Seals (Intake + Exhaust) Key Features & Benefits Designed for High Boost & High RPM Stability Engineered to maintain precise valve control under aggressive cam profiles and increased boost levels, minimizing valve float and ensuring consistent performance at high engine speeds. High-Temperature Stainless Steel Valves The Kelford valves are manufactured from premium austenitic stainless steel alloys specifically developed for high-performance engine applications. Alloy composition includes chromium, nickel, and tungsten for enhanced strength and thermal stability Excellent resistance to heat, oxidation, and fatigue under extreme exhaust gas temperatures Maintains structural integrity in high cylinder pressure and forced induction environments Triple-Groove Valve Lock Design (Drop-In Compatibility) Valves feature a precision triple-groove keeper design at the stem Fully compatible with OEM valve locks (keepers) No additional valve locks required, simplifying installation and reducing build complexity Precision Forged & Heat Treated Forged construction ensures optimal grain structure and durability Advanced heat treatment process improves tensile strength and fatigue resistance Designed for long service life in demanding conditions Beehive Valve Spring Technology Kelford’s beehive spring design offers significant advantages over traditional spring setups: Reduced valvetrain mass for improved engine response Increased stability at high RPM Lower harmonic resonance for smoother operation and reduced wear Complete Sealing Solution Includes Supertech valve stem seals for both intake and exhaust Ensures proper oil control and long-term reliability Valve Specifications Intake Valves Head Diameter: 33.90mm Stem Diameter: 5.98mm Overall Length: 104mm Tip Length: 5mm Triple-groove design – uses OEM valve locks VEHICLE FITMENT BY ENGINE VW & Audi - 2.0T FSI EA113 Engines AUDI - A4 2005-2008 (B7) 2.0T EA113 TFSI engines AUDI - A6 2005-2011 (C6) 2.0T EA113 TFSI engines AUDI - A6 Allroad 2005-2011 (C6) 2.0T EA113 TFSI engines AUDI - TT 2008-2015 (MK2 - 8J) 2.0T EA113 TFSI engines AUDI - A3 2006-2013 (MK2 - 8P) 2.0T EA113 TFSI engines VW - GTI 2006-2009 (MK5) 2.0T EA113 FSI engines VW - Jetta & Jetta GLI 2006-2010 (MK5) 2.0T EA113 FSI engines VW - Passat 2006-2010 (B6) 2.0T EA113 FSI engines VW - EOS 2006-2015 (1F7) 2.0T EA113 FSI engines VW & Audi - 2.0T TSI EA888 Gen 1/2 Engines Audi - A4 2009-2015 (B8 - B8.5) 2.0T TSI EA888 Gen 1/2 engines* Audi - A4 Allroad 2009-2015 (B8 - B8.5) 2.0T TSI EA888 Gen 1/2 engines* Audi - A5 2008-2015 (B8 - B8.5) 2.0T TSI EA888 Gen 1/2 engines* Audi - Q5 2008-2015 (8R) 2.0T TSI EA888 Gen 1/2 engines* Audi - A6 2012-2015 (C7 - C7.5) 2.0T TSI EA888 Gen 1/2 engines* Audi - TT 2008-2015 (MK2 - 8J) 2.0T TSI EA888 Gen 1/2 engines* Audi - A3 2006-2013 (MK2 - 8P) 2.0T TSI EA888 Gen 1/2 engines* Audi - Q3 2011-2015 (8U) 2.0T TSI EA888 Gen 1/2 engines* VW - GTI 2006-2009 (MK5) 2.0T TSI EA888 Gen 1/2 engines* VW - GTI 2010-2014 (MK6) 2.0T TSI EA888 Gen 1/2 engines* VW - Jetta & Jetta GLI 2010-2014 (MK6) 2.0T TSI EA888 Gen 1/2 engines* VW - SportWagen 2011-2014 (MK6) 2.0T TSI EA888 Gen 1/2 engines* VW - CC 2009-2015 (3C8) 2.0T TSI EA888 Gen 1/2 engines* VW - Passat 2006-2010 (B6) 2.0T TSI EA888 Gen 1/2 engines* VW - EOS 2006-2015 (1F7) 2.0T TSI EA888 Gen 1/2 engines* VW - Beetle 2011-2015 (MK2) 2.0T TSI EA888 Gen 1/2 engines* Exhaust Valves Head Diameter: 28mm Stem Diameter: 5.97mm Overall Length: 102mm Tip Length: 5mm Triple-groove design – uses OEM valve locks Why This Kit? Upgrading individual valvetrain components without proper matching can lead to instability and premature wear. This kit is designed as a complete system, ensuring: Correct spring pressure matched to valve mass Improved durability and reduced component stress Reliable performance across street, track, and high-power builds
